RFR: 8263915: runtime/cds/appcds/MismatchedPathTriggerMemoryRelease.java fails on x86_32

[Jie Fu]

Hi all,

runtime/cds/appcds/MismatchedPathTriggerMemoryRelease.java fails on x86_32 due to failure of this check [1].
However, this check will always fail if UseCompressedClassPointers=0 [2] (e.g., on x86_32) since the class_space_rs remains unreserved.
It would be better to fix it.

Thanks.
Best regards,
Jie
