Type: Bug
Component: hotspot
Sub-Component: compiler
Affected Version: hs24

Priority: P1

Several tests (jck-compiler and regression) fail with Java HotSpot(TM) Server VM 24.0 b24 (24.0-b24) and 1.7.0_12 b1 (1.7.0_12-ea-langtools-nightly-h357-20121107-b01-b00) on all platforms.
Last time worked with 1.7.0_12 b1 (1.7.0_12-ea-langtools-nightly-h355-20121105-b01-b00)  and Java HotSpot(TM) Server VM 23.6 b3 (23.6-b03)

This is not a real bug, it's a flag day issue.

Is this still an issue? It looks like a flag day per Christian.

Although the build says 1.7.0_12 I'm pretty sure it's a flag day issue. Can I still access the bundle somewhere?

This appears to be for jsr292, so handing this to the compiler team - you can determine if this is a flag day issue or a new bug. Perhaps in future we can find a way to avoid flag days.

And I just fcloned jdk7u-dev and built it from scratch and ran one of the failing langtools/test tests and got the same error. jdk7u-dev itself appears to be broken.

As explained by David Holmes in the previous comment this was due to the VM/JDK mistmatch. The tests were run using JDK7u10/hs24, but JDK7u12/hs24 is required. The tests ran fine the following day when the appropriate JDK/VM combination was used. I'm closing this issue as "can not reproduce"

I suspect this is the VM/JDK mismatch that was flagged to the jdk7u-dev mailing list yesterday http://mail.openjdk.java.net/pipermail/jdk7u-dev/2012-November/004925.html Subject: flag day Sender: Alejandro E Murillo alejandro.murillo at oracle.com Date: Wed Nov 7 15:53:05 PST 2012 Many apologies for the delay sending this info This afternoon I integrated hs24-b24 into jdk7u12 [1]. That integration includes the changes for JSR292 (invoke dynamic) that were integrated into jdk8 back in August. These changes require the hotspot and jdk repos to be in sync. (hotspot and jdk repos must match - i.e., either both must have the JSR292 changes or both must not have them) A JDK with mismatched repos may build but will not be able to handle invoke dynamics appropriately, and will fail with a message similar to this: $ java -showversion -Xbootclasspath/p:$PWD/classes -XX:+UnlockDiagnosticVMOptions -XX:+EnableInvokeDynamic Invalid layout of java.lang.invoke.MemberName at vmindex In particular, users of JPRT who have pulled the changes must build both hotspot and jdk until the JSR292 changes are in a promoted jdk7u12 build (expected tomorrow, Thu, November 8, 2012). The simplest coping strategy is to avoid pulling from the jdk7u master repo until the next jdk7u12 build is promoted. If you do pull, make sure to pull both hotspot and jdk, and to build both.
