RFR: 8321422: Test gc/g1/pinnedobjs/TestPinnedObjectTypes.java times out after completion

[Thomas Schatzl]

Hi all,

  please review this change that disables core file creation for the subtests of this test that check for assertion failure. Core dump creation can make the whole test time out.


----------System.out:(54/8466)----------
Command line:... -XX:+UseG1GC -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:. -Xmx32M -Xmn16M -Xlog:gc gc.g1.pinnedobjs.TestObjectPin Object ]
[2023-12-05T23:30:37.930237Z] Gathering output for process 98165
[0.066s][info][gc] Using G1
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/open/src/hotspot/share/gc/g1/g1CollectedHeap.inline.hpp:268), pid=98165, tid=6403
#  assert(obj->is_typeArray()) failed: must be typeArray

[2023-12-05T23:35:20.308715Z] Waiting for completion for process 98165
[2023-12-05T23:35:20.632162Z] Waiting for completion finished for process 98165

Notice the 5 min delay from the `Gathering output for process` to the `Waiting for completion finished` message. This repeats for the second test, triggering the timeout.

Testing: failing test

Thanks,
  Thomas
