To capture the current Java™ state from a Java program, Z Abend Investigator can be invoked to create a history file fault entry, along with an associated MVS™ SVC dump.
Z Abend Investigator Java wrapper utility wraps a callable Java application in a try-catch block by using the FA Java class.
Z Abend Investigator provides a JVMTI (JVM Tool Interface) agent. The agent runs inside a Java™ Virtual Machine (JVM) and can inspect the state of the running Java application.
When the JCLcapture option is in effect during real-time processing, Z Abend Investigator attempts to obtain the JCL and save it in the fault entry. This feature is available with JES2 only.
The following describes the entry and return specifications for HFZSNAP.
