> 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
