Hi all,
vmTestbase/gc/gctests/StringInternGC/StringInternGC.java fails with release VM on our many-core machines due to `-XX:MaxRAMPercentage=0`.
This is because `-XX:MaxRAMPercentage=0` will be 0 if JTREG_JOBS > 25 [1].
Reproduce:
- make test TEST="vmTestbase/gc/gctests/StringInternGC/StringInternGC.java" JTREG="JOBS=26" CONF=server-release
`-Xmx1g` is added to make it more robust.
Note: we still see failure with `-Xmx512m`.
Thanks.
Best regards,
Jie
