Local fix
Use different GC policy. Do not use agent
Problem summary
In certain conditions Partial GC in Balanced might occur earlier than the dedicated GC Master Thread is started. This is normal behavior however the initialization of hooks required for the functioning of JVMTI might be not complete and can be a reason for assertion.
Problem conclusion
The initialization of hooks is now completed earlier. . This APAR will be fixed in the following Java Releases: 8 SR3 FP21 (8.0.3.21) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs. For those running stand-alone, information about the available Service Refreshes and Fix Packs can be found at: https://www.ibm.com/developerworks/java/jdk/
