Grumble. It used to be that you could edit SpawnOfWotaskd.sh, and
then do a "kill -QUIT <pid>" on your application to get a thread
dump. On Leopard Server, this does not seem to produce any output.
It still works for applications running in Eclipse. I am not sure yet
if this is a Client vs Server issue or a Development vs Deployment
issue. At first I thought it was just one machine, but I have
reproduced this on a different machine now. If I run the app from the
command line, I can set the thread dump. That suggests the problem
lies in wotaskd launched processes.
Has anyone else noticed this? Any solutions? I know about jstack
but, sigh, it is also defective on Leopard (or is that Apple's Java
1.5?) in that it can't print the correct thread names.
