RFR: 8266422: GC ergo tests should not write cores

[Thomas Stuefe]

Hi,

unrelated crashes in GC tests showed timeouts and large core files on AIX, which unfortunately has no concept of committing memory - reserved memory counts toward the commit charge right away and hence are reflected in core file size.

Therefore I would like to run these tests without cores. Note that it is not my intention to fix up all potential tests which do this, which would be a much larger task, or would require a change at a lower layer (e.g. always pass -CreateCoredumpOnCrash to createJavaProcessBuilder).

Thanks, Thomas
