Revert^4 "JVMTI PopFrame support"
This reverts commit 202b617acf477e8e8e11915f467120a0bd518e74.
This unreverts commit 202b617acf.
This unreverts commit 88a2a9d7a1.
There were several bugs with the implementation of pop-frame related
to interactions between the jit, exception handling, class-loading,
and deoptimization.
- We were instrumenting the target thread stack in cases where it was
unnecessary which caused the exception handler to incorrectly
determine that a method was not deoptimizable. This caused the
pop-frame to be ignored.
- We were incorrectly sending ExceptionCatch events if an exception
suppressed by pop-frame would have been caught in the current frame.
- We were allowing pop-frame to be used on threads suspended in the
ClassLoad or ClassPrepare events despite having surprising semantics
in that situation (see b/117615146).
Needed to modify test 1953 slightly for inclusion in CTS. I needed to
make the CTS entrypoint not run the class-load tests (since the cts
configuration means the classes are loaded by the verifier and not the
interpreter). I updated the expected.txt and check script to reflect
this.
Reason for revert: Fixed issue causing Exception events to sometimes
eat PopFrame and other issues.
