problem: 1) ciEnv::register_method() calls CodeCache::handle_full_code_cache() in a block where no safepoints are allowed. However, handle_full_code_cache can reach a safepoint since it uses locks. 2) I added a check in 'possibly_sweep()' that ensures that only compiler threads can sweep the code cache. It can happen that normal Java threads can call 'possibly_sweep()' via 'handle_full_code_cache()'. solution: 1) move call to 'handle_full_code_cache()' outside the block where no safepoints are allowed 2) see above testing: failing test case passes.

ILW=HMM=P2 I: High, Test hangs L: Medium, Reproduces more often with -XX:+DeOptmizeALot but otherwise is intermittent W: Medium, larger code cache reduces the likelihood but not always 8-critical-request: NSK regression failures, these should be fixed for JDK8 release criteria.

Uses -XX:+DeoptimizeALot.
