[aarch64-port-dev ] Fwd: Compact strings enablement - JTreg runs

[Stuart Monteith]

Looking more closely, the errors are:

  0: JTwork-compactoff  pass: 5,840; fail: 1,793; error: 21; not run: 331
  1: JTwork-compacton  pass: 5,836; fail: 1,793; error: 25; not run: 331

There were timeouts, etc. I tried rerunning the failing tests again,
and with compact strings on and off, I inconsistently get:

Passed: sun/security/provider/SecureRandom/StrongSecureRandom.java
Passed: java/awt/Dialog/CloseDialog/CloseDialogTest.java
Passed: java/lang/instrument/PremainClass/NoPremainAgentTest.java
Passed: java/rmi/server/RMISocketFactory/useSocketFactory/unicast/UseCustomSocketFactory.java

FAILED: java/util/concurrent/tck/JSR166TestCase.java
Passed: tools/launcher/ArgFileSyntax.java
Passed: java/util/stream/boottest/java.base/java/util/stream/SpinedBufferTest.java
Test results: passed: 7; failed: 1

The JSR166TestCase.java fails with:
JavaTest Message: JUnit Failure: testInvokeAll1(ForkJoinTaskTest):
ExecutorService java.util.concurrent.ForkJoinPool at 234bf9ce[Shutting
down, parallelism = 48, size = 20, active = 1, running = 0, steals =
23, tasks = 0, submissions = 0] did not terminate in a timely manner

On another run JSR166 simply times out completely, and in another is
passed fine. An intermittent failure of a concurrency test - worrying?

The failures I find are not /obviously/ affected by CompactStrings.

Regards,
    Stuart
