Error description
Error Message: Abend S0C8 or Program-Interruption Code 0008 (Fixed Point Overflow Exception) triggered from maxprec routine. . Stack Trace: maxprec j9time_current_time_millis jitHookBytecodeProfiling J9HookDispatch flushBytecodeProfilingData bytecodeLoop+0000357E RUNCALLINMETHOD gpProtectedRunCallInMethod signalProtectAndRunGlue j9sig_protect_ceehdlr gpProtectAndRun gpCheckCallin callStaticVoidMethod . The original Fixed Point Overflow Exception in maxprec may be masked by a Language Environment Abend U4036 with reason code 1 (U4036-1). In this case, the EPIE stored in Register 2 at the time of the U4036 abend will contain details of the actual exception.
Local fix
Problem summary
Use of signed instead of unsigned subtraction for a particular instruction in the systemZ platform routines to calculate current time caused the fixed point overflow trap to be triggered if the Fixed Point Overflow mask happened to be set (for e.g. via JNI code).
Problem conclusion
The jvm has been changed to use unsigned subtraction as appropriate, and thus avoid triggering fixed point overflow exceptions. . This APAR will be fixed in the following Java Releases: 8 SR5 FP5 (8.0.5.5) . 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/
