Java event replacement in Fault Analyzer event list
When an abend includes Java™ events, Fault Analyzer requests a system dump of the JVM. This Java™ system dump is analyzed by Fault Analyzer using Diagnostic Tool Framework for Java (DTFJ) APIs.
The DTFJ processing occurs asynchronously and does not delay the initial real-time abend analysis. This means that the real-time Fault Analyzer report contains only internal JVM events, not Java™ events.
When DTFJ processing has completed, the additional Java™ information is added into the fault entry so when reanalysis of the fault entry is performed, the more concise and useful Java™ event information is shown instead.
For example, the real-time event summary might show the following:
