[jdk11u-dev] RFR: 8217850: CompressedClassSpaceSizeInJmapHeap fails after JDK-8217612

[toshiogata]

Hi all,

This is a backport of JDK-8217850: CompressedClassSpaceSizeInJmapHeap fails after JDK-8217612

I worked for backporting JDK-8217612, and found that this related patch should be backported at the same time.

The riginal patch is applied cleanly to JDK-8217612 applied code.

Testing: all serviceability agent tests, hotspot_all that includes CompressedClassSpaceSizeInJmapHeap.java and the test which come with JDK-8217612.

Thank you.
