The flag -XX:+UseLargePagesInMetaspace was added in the fix for:
8024547: MaxMetaspaceSize should limit the committed memory used by the
metaspaces
However, we currently have no continuously running tests that turn this
flag. The added tests, TestSystemGC.java, does the bare minimum and
starts the JVM with -XX:+UseLargePagesInMetaspace and calls System.gc().
I've taken the liberty of creating a generic System.gc() test instead of
a more specialized UseLargePagesInMetaspace tests, and added some extra
run targets to run System.gc() with our different GCs.
thanks,
