SharedClasses.SCM01 Copy sharedClasses jar fails about openj9 HOT 6 CLOSED

The directory /home/jenkins/testDependency/system_lib/sharedClassesTestData/v1/jdk22 exists, but classes.jar doesn't exist. The subdirectory net/openj9/sc/classes/ exists and is full of classes. Probably there is a logic error and if the test finds something, it expects classes.jar to exist. There were some machines that ran out of space, this may have been one of them. Deleted jdk22 and hopefully that fixes it.

@LongyuZhang pls take a look. I suspect this has something to do with the changes to preserve the shared test classes (eclipse-aqavit/openj9-systemtest#156), and cache the system test jar files.

The xlinux machines weren't available so we've only recently been able to resume testing on this platform. We don't have a last working / first failing build.

I do see console output 09:05:49 GEN /home/jenkins/testDependency/system_lib/sharedClassesTestData/v1/jdk22 exists, suspect the folder exists, but the classes.jar doesn't exist inside it. @annaibm Could you run this test, keep Workspace and ReportDir, then reserve the machine to check if classes.jar is there, if not check if it generated in other places. thanks.

Ran the extended.system tests under the following scenarios on the machine rhel9x86-svl-rt1-1.fyre.ibm:

1. When /home/jenkins/testDependency/system_lib/sharedClassesTestData/v1/jdk22 did not exist - 42017

All tests passed in both scenarios.

from openj9.

@annaibm has tested multiple scenarios with test SharedClasses.SCM01.SingleCL, all passed:

• no pre-stage folder: hyc_grinder 42011
• with pre-stage folder system_lib, but no sub-folder sharedClassesTestData/v1/jdk22: hyc_grinder 42012
• with pre-stage folder sharedClassesTestData/v1/jdk22 and classes.jar: hyc_grinder 42013

Suspect the folder sharedClassesTestData/v1/jdk22 created by other tests, but classes.jar not generated or being deleted after that test completes, so running extended.system as target to test now.

Both failures occurred on the same machine, I'll take a look at it.
