jdmpview has incorrect register contents on z/OS #6005

Open sehirst opened 5 years ago

Reading a core dump generated by traditional Websphere Application Server from a segfault/0C4 abend/GPF, using info thread, the correct thread is selected but all the registers including the PSW do not have the values from the context of the crash, and thus are not useful.

What tool did you use to determine the correct register values?

sehirst commented 5 years ago

The most reliable is IPCS. The internal tool KCA also gets the correct register values (with one small mistake with the PSW). The javacore also has the correct values.
