It starts to fail after PPC64 integration.
Comments
Added 8u60 to the "Affected Versions". This backport is necessary to make the 8046246 backport applied cleanly. It is also nice to fix this issue in 8u60 by itself.

The failing guarantee was added by the following fix: https://bugs.openjdk.java.net/browse/JDK-7182152 changeset: 4127:8d9fc28831cc parent: 4094:f3ea1af9207a user: dcubed date: Wed Feb 06 14:31:37 2013 -0800 summary: 7182152: Instrumentation hot swap test incorrect monitor count I have a concern about its full correctness.

One more detail to the puzzle... The Aurora copy of the SQE testbase has inconsistency between the original and redefined version of the class INDIFY_Dummy0. The original (non-redefined) class has these 3 methods in the class file (the redefined class does not): MT_bootstrap(), MH_bootstrap(), INDY_call() : % /net/sc11152541/export/home/sspitsyn/hs25/hsx1/solaris-sparcv9/bin/javap -private -classpath /net/aurora-ds.us.oracle.com/data/export/aurora/sca/vmsqe/testbase/vm/9/build/execution/vm/bin/classes vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 Compiled from "INDIFY_Dummy0.java" public class vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 { private static java.lang.invoke.MethodHandle INDY_call; public vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0(); private static java.lang.invoke.MethodType MT_bootstrap(); private static java.lang.invoke.MethodHandle MH_bootstrap() throws java.lang.NoSuchMethodException, java.lang.IllegalAccessException; public static java.lang.invoke.CallSite bootstrap(java.lang.invoke.MethodHandles$Lookup, java.lang.String, java.lang.invoke.MethodType) throws java.lang.Throwable; public static java.lang.Boolean target(java.lang.Object, java.lang.String, int); public static void redefineNow(); private static java.lang.invoke.MethodHandle INDY_call() throws java.lang.Throwable; public static boolean invokeTarget() throws java.lang.Throwable; private static boolean invokeTarget0() throws java.lang.Throwable; public static boolean isRedefinedClass(); } The most strange detail is that in my own SQE testbase build both the original class file and the redefined miss these 3 methods: % /net/sc11152541/export/home/sspitsyn/hs25/hsx1/solaris-sparcv9/bin/javap -private -classpath /net/sc11152541/export/home/sspitsyn/utb9/vm/bin/classes vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 Compiled from "INDIFY_Dummy0.java" public class vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 { private static java.lang.invoke.MethodHandle INDY_call; public vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0(); public static java.lang.invoke.CallSite bootstrap(java.lang.invoke.MethodHandles$Lookup, java.lang.String, java.lang.invoke.MethodType) throws java.lang.Throwable; public static java.lang.Boolean target(java.lang.Object, java.lang.String, int); public static void redefineNow(); public static boolean invokeTarget() throws java.lang.Throwable; private static boolean invokeTarget0() throws java.lang.Throwable; public static boolean isRedefinedClass(); } % /net/sc11152541/export/home/sspitsyn/hs25/hsx1/solaris-sparcv9/bin/javap -private -classpath /net/sc11152541/export/home/sspitsyn/utb9/vm/bin/newclass vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 Compiled from "INDIFY_Dummy0.java" public class vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 { private static java.lang.invoke.MethodHandle INDY_call; public vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0(); public static java.lang.invoke.CallSite bootstrap(java.lang.invoke.MethodHandles$Lookup, java.lang.String, java.lang.invoke.MethodType) throws java.lang.Throwable; public static java.lang.Boolean target(java.lang.Object, java.lang.String, int); public static void redefineNow(); public static boolean invokeTarget() throws java.lang.Throwable; private static boolean invokeTarget0() throws java.lang.Throwable; public static boolean isRedefinedClass(); } It looks to me, the SQE testbase needs to be rebuilt and reinstalled to the Aurora location. Probably, the new cat/sub-cat are not fully correct as it needs to reflect the SQE infrastructure area. But I leave it to the VM SQE engineers. Kirill, I temporarily assigned this issue to you as you are the author of these tests. Could you, please, take a look what is wrong with the class files preparation? Also, please, re-assign it back to me as there is still issue on the JVMTI side. We may need to create another bug for the SQE infrastructure issue. However, I hope, it will be resolved automatically after the new SQE testbase release deployment.

A part of this issue is still on the hotspot/jvmti side. If a class redefinition deletes some private methods from the class then only one of the invariants must be true: 1. The removed methods should not be present in the constant pool cache 2. The guarantee in the VM_RedefineClasses::CheckClass::do_klass() must be relaxed: 3614 guarantee(false, "OLD and/or OBSOLETE method(s) found");
06-05-2014
Ok, it seems, these 3 methods are deleted by the indify-tool. I've found the following fragment in my SQE testbase build log: indify-tool: [echo] Indify: /net/sc11152541/export/home/sspitsyn/utb9/vm/bin/pre-indify/newclass/vm/mlvm/indy/func/jvmti/mergeCP_indy2manyDiff_a/INDIFY_Dummy0.class -> /net/sc11152541/export/home/sspitsyn/utb9/vm/bin/pre-sde/newclass/vm/mlvm/indy/func/jvmti/mergeCP_indy2manyDiff_a/INDIFY_Dummy0.class [java] patching vm/mlvm/indy/func/jvmti/mergeCP_indy2manyDiff_a/INDIFY_Dummy0.invokeTarget0()Z [java] 15:invokestatic 46 INDY_call()L;...; 21:invokevirtual 47 => invokedynamic 172:InvokeDynamic[0, 170] [java] 29:invokestatic 46 INDY_call()L;...; 35:invokevirtual 47 => invokedynamic 172:InvokeDynamic[0, 170] [java] 75:invokestatic 46 INDY_call()L;...; 81:invokevirtual 47 => invokedynamic 172:InvokeDynamic[0, 170] [java] 90:invokestatic 46 INDY_call()L;...; 96:invokevirtual 47 => invokedynamic 172:InvokeDynamic[0, 170] [java] 105:invokestatic 46 INDY_call()L;...; 111:invokevirtual 47 => invokedynamic 172:InvokeDynamic[0, 170] [java] pattern methods removed: [MT_bootstrap()L, INDY_call()L, MH_bootstrap()L] [java] wrote /net/sc11152541/export/home/sspitsyn/utb9/vm/bin/pre-sde/newclass/vm/mlvm/indy/func/jvmti/mergeCP_indy2manyDiff_a/INDIFY_Dummy0.class I guess, the indify-tool must be used consistently to equally indify both the original and redefined class files, so that, both versions have these 3 methods removed: MT_bootstrap(), INDY_call(), MH_bootstrap()
06-05-2014
Something is wrong with the aurora copy of the testbase build as the source and binary of the newclass/INDIFY_Dummy0.java do not match: The javap shows just 7 methods in the newclass/ class file /INDIFY_Dummy0.class from the build: INDIFY_Dummy0(), bootstrap(), target(), redefineNow(), invokeTarget(), invokeTarget0(), isRedefinedClass() : % /net/sc11152541/export/home/sspitsyn/hs25/hsx1/solaris-sparcv9/bin/javap -private \ ? -classpath /net/aurora-ds.us.oracle.com/data/export/aurora/sca/vmsqe/testbase/vm/9/build/execution/vm/bin/newclass \ ? vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 Compiled from "INDIFY_Dummy0.java" public class vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0 { private static java.lang.invoke.MethodHandle INDY_call; public vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a.INDIFY_Dummy0(); public static java.lang.invoke.CallSite bootstrap(java.lang.invoke.MethodHandles$Lookup, java.lang.String, java.lang.invoke.MethodType) throws java.lang.Throwable; public static java.lang.Boolean target(java.lang.Object, java.lang.String, int); public static void redefineNow(); public static boolean invokeTarget() throws java.lang.Throwable; private static boolean invokeTarget0() throws java.lang.Throwable; public static boolean isRedefinedClass(); } However, the source file newclass/INDIFY_Dummy0.java cached in the test working directory should have 10 methods: MT_bootstrap(), MH_bootstrap(), INDY_call(), INDIFY_Dummy0(), redefinenow(), invokeTarget(), invokeTarget0(), bootstrap(), target(), isRedefinedClass(): cat -n /net/sc11152541.us/export/home/sspitsyn/bug/8033684/v9/ResultDir/mergeCP_indy2manyDiff_a/newclass/INDIFY_Dummy0.java 1 package vm.mlvm.indy.func.jvmti.mergeCP_indy2manyDiff_a; 2 3 import java.lang.invoke.CallSite; 4 import java.lang.invoke.ConstantCallSite; 5 import java.lang.invoke.MethodHandle; 6 import java.lang.invoke.MethodHandles; 7 import java.lang.invoke.MethodType; 8 9 import vm.mlvm.share.MlvmTest; 10 11 public class INDIFY_Dummy0 { 12 13 private static MethodType MT_bootstrap() { 14 return MethodType.methodType(CallSite.class, MethodHandles.Lookup.class, String.class, MethodType.class); 15 } 16 17 private static MethodHandle MH_bootstrap() throws NoSuchMethodException, IllegalAccessException { 18 return MethodHandles.lookup().findStatic( 19 INDIFY_Dummy0.class, 20 "bootstrap", 21 MT_bootstrap()); 22 } 23 24 public static CallSite bootstrap(MethodHandles.Lookup l, String name, MethodType mt) throws Throwable { 25 MlvmTest.getLog().display("Redefined bootstrap(): Lookup " + l + "; method name = " + name + "; method type = " + mt); 26 CallSite cs = new ConstantCallSite(l.findStatic(INDIFY_Dummy0.class, "target", mt)); 27 return cs; 28 } 29 30 public static Boolean target(Object o, String s, int i) { 31 MlvmTest.getLog().display("Redefined target called!

I'm moving this bug to the qe_test/hotspot category/sub-category and requesting the SQE guys to take a look and check what is going on with the Aurora copy of the SQE testbase. Please, feel free to move this bug back to the development if the SQE infrastructure is Ok and the artifact above can be somehow explained.
06-05-2014
Ok, the difference is in the testbase build that is used. When I run with the short name 'ute' then it is defaulted to one of the old VM testbase builds. The option -testbase /net/aurora-ds.us.oracle.com/data/export/aurora/sca/vmsqe/testbase/vm/9/build/execution/vm forces to use the same testbase build as used in the nightly.

Thanks, Vladimir! It helped to reproduce the issue. Now I wonder, what is the difference? Will try to discover.

Coleen reminded me about that this bug. I've not really worked on it yet. Returning to it.

I'm not able to reproduce this issue yet. Used the following set of flags on both solaris-sparcv9 and solaris-amd64: -vmopts '-server -Xcomp -ea -esa -XX:-TieredCompilation -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:TraceRedefineClasses=16384' \
01-05-2014
I'm looking into this issue. Will try to isolate the push caused this regression.

Moving from hotspot/svc -> hotspot/jvmti since this assertion failure indicates that JVM/TI RedefineClasses() is broken.
