Local fix
-Xjit:disableRedundantAsyncCheckRemoval would work around the functional issue
Problem summary
Internal testing has uncovered a functional bug (hang) due to improper placement of asyncchecks. This leads to a hang when we wait for a particular thread to yield and it gets stuck inside a loop (while this bug can happen anywhere with the necessary bytecode pattern we have only seen it in ForkJoin code) not being able to yield because there is no asynccheck.
Problem conclusion
This defect will be fixed in: 7.0.0 SR5 6.0.1 SR6 6.0.0 SR14 5.0.0 SR16 FP3 . The JIT has been updated to eliminate the problem with async check placement.
Temporary fix
