IBM Diagnostic Tool Framework for Java Version 1.11

The Diagnostic Tool Framework for Java (DTFJ) is a Java application programming interface (API) used to support the building of Java diagnostics tools.

You must run jextract on the system that produced the dump. (For more information on jextract see the Diagnosis documentation.)

The DTFJ API helps diagnostics tools access the following information:
