Errors

MethodHandles.collectArguments issues that are seen when OJDK MHs are enabled in OpenJ9.

Failing Test Targets

1. JCL_Test_* [sanity.functional]
   • test_CollectArgumentsNegative
   • test_VoidCollectArgumentsNegative

Repetitions of the above error are seen because the test target is run with different JVM arguments.

Steps to build an OpenJ9 JDK with OJDK MHs enabled

Refer to #11458.

OpenJDK bug: https://bugs.openjdk.java.net/browse/JDK-8259922

Fix: ibmruntimes/openj9-openjdk-jdk@ab6b9c3

Only available in JDK-next. Needs to be back-ported to JDK8, JDK11 and JDK16.

This should be tagged with the project:MH label.

[fengxue-IS]

Still needs to be back-ported to JDK8, JDK11 in the future once we are ready to enable OJDK MH for these versions.
As this is fixed for Java17+, marking this low priority

Backported to JDK8 and JDK11:

• Backport 8259922: MethodHandles.collectArguments does not throw IAE ibmruntimes/openj9-openjdk-jdk8#560
• Backport 8259922: MethodHandles.collectArguments does not throw IAE ibmruntimes/openj9-openjdk-jdk11#502
