Hi Roman,
I'll have a look at this, although it might not be for a few days. In
the meantime, maybe you can describe your new implementation in
classTrack.c so it's easier to look through the changes.
thanks,
Chris

Hello all,
Issue:
https://bugs.openjdk.java.net/browse/JDK-8227269
I am proposing what amounts to a rewrite of classTrack.c. It avoids
throwing away the class cache on GC, and instead keeps track of
loaded/unloaded classes one-by-one.
In addition to that, it avoids this whole dance until an agent
registers interest in EI_GC_FINISH.
Webrev:
http://cr.openjdk.java.net/~rkennke/JDK-8227269/webrev.01/
Testing: manual testing of provided test scenarios and timing.
Eg with the testcase provided here:
https://bugzilla.redhat.com/show_bug.cgi?id=1751985
I am getting those numbers:
unpatched: no debug: 84s with debug: 225s
patched: no debug: 85s with debug: 95s
I also tested successfully through jdk/submit repo
Can I please get a review?
Thanks,
Roman
