RFR(S): 8247762: [aarch64] Timeout in .../HeapDumpTestWithActiveProcess.java due to inf. loop in AARCH64CurrentFrameGuess.run()

[Patric Hedlin]

Dear all,

I would like to ask for help to review the following change/update:

Issue:  https://bugs.openjdk.java.net/browse/JDK-8247762
Webrev: http://cr.openjdk.java.net/~phedlin/tr8247762/


AARCH64CurrentFrameGuess.run() may loop indefinitely in a bad 
stack-walk. This is JDK-8231635 applied to AArch64.

NOTE: This patch is only a partial solution to the various 
/stack-walk/timeout/ issues in this particular test-case.


Testing: HeapDumpTestWithActiveProcess.java


Best regards,
Patric
