Antonio Sanso updated KATO-14:
------------------------------
Attachment: KATO-14-asanso-patch.txt
Providing patch containing a StackDumpWriter. it still has some
issues/limitation mainly due
public List<JavaReference> getHeapRoots() {
return Collections.emptyList();
}
that should provide information related references to other threads (e.g.
Locked ownable synchronizers) but I think is a good starting point.
> Provide new threads dump writer in order to be compatible with common thread
> analyzers

> At the moment Kato has an XMLDumpWriter that produces an xml file containing
> all the threads information. This is not compatible with most of the standard
> threads dump analyzers (e.g. TDA [0], samuray) that expect a file that has a
> format like:

> I'll provide a patch containing a StackDumpWriter providing an output
