Local fix
Problem summary
When a native application creates a Java Virtual Machine (JVM) instance through JNI, the JVM's SIGABRT handler overrides the native application's SIGABRT handler, which is installed prior to creating the JVM instance. If a SIGABRT is received by the native application, only the JVM's SIGABRT handler will be invoked and the native application's SIGABRT handler will not be invoked.
Problem conclusion
A new JVM option -XX:<OSB>+<PIPE>-<CSB>HandleSIGABRT is introduced. When the option is enabled (default behavior), the JVM handles the signal SIGABRT and generates the various dump files. When the option is disabled (-XX:-HandleSIGABRT), the JVM does not handle the signal SIGABRT. Explicitly enabling -XX:+HandleSIGABRT with -Xrs is not supported. An error is thrown if both options are enabled together. . This APAR will be fixed in the following Java Releases: 8 SR6 FP15 (8.0.6.15) . 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/
Temporary fix
Enable the JVM option -Xrs:sync. The JVM will not register a signal handler for SIGABRT, and the application signal handler will be invoked if installed. If not installed, the operating system will handle the signal. It should also be noted that IBM J9 won't register a signal handler for other signals such as SIGBUS, SIGILL, SIGFPE, SIGTRAP and SIGABEND when -Xrs:sync is specified. -Xrs should be used if the native application wants to completely disable JVM signal handling.
