Hi Arno,

this testfix seems reasonable, +1.

You’ve posted it to the wrong mailing list, though. It should be directed to hotspot-compiler-dev, hence I’ve copied this list in my reply. Bcc-ing compiler-dev.

Best regards

Hi Arno,

Seems reasonable, assuming you verified that 64m heap are enough for this test on all platforms.

I can sponsor this for you.

Cheers, Thomas

I have seen some occurrences of this issue (8230110) on our AIX and Windows test machines. The test times out because it writes a huge core file (I have seen more than 24GB on one machine) and this might take minutes.
As far as I understand the test does not need a core file. Therefore my suggestion is to set a max java heap size (-Xmx64m) and switch of core file writing (-XX:-CreateCoredumpOnCrash).

I am no committer – I will need a sponsor for this change.

Best regards,
