Subject OpenJ9 support thoughts ?
Date Thu, 14 Feb 2019 19:10:02 GMT
Any thoughts on support for OpenJ9 (IBM JRE open sourced via eclipse as runtime in OpenJDK8)
?

The first issue that I’ve seen is a different naming scheme of GC pools in the MemoryPoolMXBean
registration (tenured-SOA and tenured-LOA), names that are not currently checked by Geode
for heap expiration.  A potential workaround is to use the -xx:+HeapManagementMXBeanCompatibility
option which sets the name to “Java heap” which is checked by Geode.  However, more investigation
of the breakdown of the GC pools is in order to make sure what Geode is checking is what is
desired. Another alternative workaround is to set the gemfire.ResourceManager.HEAP_POOL directly
with tenured-LOA, although neither workarounds are probably the best answer.
