RFR [jdk11]: 8212200: assert(on_stack()) failed when shared java.lang.object is redefined by JVMTI agent

Tue Jun 30 07:36:18 UTC 2020

Hello, please review  the jdk11 backport of  8212200 .

I had to do a few slight adjustments to adjust the src  changes of  8212200   to jdk11 .

The test ( test/hotspot/jtreg/runtime/SharedArchiveFile/serviceability/ReplaceCriticalClasses.java.)  from the original jdk/jdk webrev  of 8212200   did not work.
So I had to include adjustments from 8221918 and 8213275  to fix  the test .
