Error description
Error Message: N/A . Stack Trace: N/A .
Local fix
-Xjit:disableRedundantAsyncCheckRemoval will turn off the JIT optimization that erroneously eliminates async checks.
Problem summary
The redundant async check removal optimization was incorrectly eliminating async checks from some loops that had multiple back edges, e.g. a loop in juc ForkJoin code that had continue statements was causing the analysis to go wrong.
Problem conclusion
This defect will be fixed in: 6.0.0 SR15 6.0.1 SR7 7.0.0 SR6 5.0.0 SR16 FP4 . Redundant async check removal was fixed to eliminate GC yield points correctly.
Temporary fix
