Description
Related to https://bugs.openjdk.java.net/browse/JDK-8233453 task.
(MLVM deoptimize stress test timed out)

## test - [open/test/hotspot/jtreg/vmTestbase/vm/mlvm/meth/stress/compiler/deoptimize/Test.java] 

It seems the intermittent timeouts of the test
(mostly with solaris-sparc and sometimes with windows-x64)
started with jdk-13+17, with fix changeset of -
  https://bugs.openjdk.java.net/browse/JDK-8221393
  ResolvedMethodTable too small for StackWalking applications
(could not get any timeout failure for the test with sources updated to jdk-13+16 or updated to changeset version just before 8221393 fix.)

At present plan is to fix the other JDK-8233453 task by increasing the timeout factor of the test.
Opening this task to check if the slowdown of the test after JDK-8221393 is expected!

Comments
I don't see any connection between this test and the resolved method table. I reran this on windows and it didn't fail. I'm closing as CNR.

With New Invoke Bindings the RMT goes away.
