Local fix
Problem summary
Assertion occurs when GC threads terminate the scan loop as quickly as possible which may skip to flushing the buffers during an abort scenario
Problem conclusion
The assertions that ensures the local buffers at the end of scan loop are empty should be relaxed to ignore the scenario if the scan loop is aborted . This APAR will be fixed in the following Java Releases: 8 SR6 FP5 (8.0.6.5) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
