Prototype fix for this appears to also fix the following: jck8 test of api/java_util/TreeSet/ParallelStream.html I hit an assert when doing CHA for a default method during JIT-compilation: # Internal Error (src/share/vm/code/dependencies.cpp:1411) # assert(wf.check_method_context(ctxk, m)) failed: proper context Call stack: Dependencies::find_unique_concrete_method ciMethod::find_monomorphic_target Compile::optimize_inlining Compile::optimize_virtual_call Parse::do_call

After several prototypes, current proposal is to simplify how default methods are handled by 1) not using overpasses for default methods, not using a second step invokespecial - this removes the problem with invokespecial's constant pool lookup that requires class access 2) creating default_methods array in the inheriting instanceKlass with public default methods 3) search order: current class methods, super classes methods, default methods, transitive interfaces 4) adding the default method to the vtable directly, with the default method having the correct method holder, which allows the permission and loader constraint tests to work on the correct method holder/class loader 5) overpasses are still used for AME for conflicts with default methods, these are still added to the local method and constant pool (future potential for optimizations here)
22-08-2013
Now that we have agreed that the JVM is not generating bridges, and is not handling generic signatures and covariant returns, the JVM no longer needs to create overpass methods to contain the appropriate check casts. The fix is for the JVM to determine the appropriate default methods and to track those in inheriting class, and include them in the vtable inheritance, maintaining the original methods and the method-holder (i.e. the interface which defines the default method). This means that both the access checking and the loader constraint checking will be done against the correct method and method-holder, i.e. class. The JVM does create overpasses to handle the error conditions, for example if there are conflicting default methods, then we need a new method to enable us to throw the appropriate error and error message. Checking in the fix under this bug, which also fixes 80013085.

A similar example to address; in this case, the VM-generated invokespecial instruction (in B) needs to refer to the superclass (A), not a superinterface. package p1; interface I { public default int m() { return 12; } } package p2; public interface J {} /* Note: unrelated to I */ package p1; public class A implements I {} package p2; public class B extends A implements J {}

Adding test case names to have them matched in Aurora runs: lang/CLSS/clss475/clss47501m21/clss47501m21 lang/CLSS/clss475/clss47501m211/clss47501m211
23-04-2013
Suggested fix: change the code generated in each default method "overpass" so that it names a direct super of the current class, and leave it to resolution find the actual declaration. (Thanks to the 'implements' clause, we already know that the direct supers are accessible.)

Two JCK8 tests failures seems to be related: lang/INTF/intf024/intf02402m01/intf02402m01.html lang/INTF/intf024/intf02402m11/intf02402m11.html

The bridge is generated according to 6342411. It is _not_ related to overriding.
05-03-2013
I though maybe I'd missed something here, and the method really is accessible. I note that the javap output for the counterexample we're using includes a bridge method, which might explain why it doesn't produce the same error: package a; class A { public int m() { return 12; } } package a; public class B extends A { /* bridge goes here*/ } package b; public class C extends a.B {} System.out.println(new b.C().m()); --- public class a.B extends a.A { ... public int m(); flags: ACC_PUBLIC, ACC_BRIDGE, ACC_SYNTHETIC Code: stack=1, locals=1, args_size=1 0: aload_0 1: invokespecial #2 // Method a/A.m:()I 4: ireturn LineNumberTable: line 1: 0 } --- However, everything works fine if I replace B with an equivalent class that has no bridge. (Maybe the bridge serves some other purpose...?) Anyway, method resolution (JVMS 5.4.3.3) does specify an IAE, but only if the _named_ class is inaccessible or the _resolved_ method is inaccessible. The class/interface of the resolved method is irrelevant to this access check (see JVMS 5.4.4).

Seems like an hotspot problem with default method calls - the following similar program compiles and runs without problems: package p1; class Sup { public void m() { } } public class Sub extends Sup { } package p2; class Foo extends p1.Sub { } Foo foo = new Foo(); foo.m(); //ok In both cases javac emits an invokevirtual to Foo.m().
