Re: Followup to Java apps Hanging on Jaguar

Hi Ron,

I ran Sampler and saved the report. I don't really know how to tell for sure
if the JVM is launched or the Carbon event loop started. Several threads
have JVM_GetClassMethodsCount at the top, another runFromPropertiesList,
another initializeStandaloneThread followed by RunApplicationEventLoop. Not
signs that my application has been called.

I couldn't get anywhere with gdb. It hung on "Reading symbols for shared
libraries.." Actually, the whole Terminal.app hung :-( I couldn't even force
quit Terminal... Logged in remotely and tried killing it from the command
line and that failed too. Didn't see a gdb process running. Had to use the
Windows-ish salute to clean it up :-(

If the app is hung *and* you have the +PrintJavaStackAtFatalState option set, try disabling that option. If there's a native code crash and then the JVM crashes whilst trying to print the Java stack, it tries to handle its own exception, and, since that thread is busy, you get the idea ...

One possibly interesting thing is all the threads seem to send with
JVM_NewInstance.

Since we strip most symbols out, this is probably misleading (but given the pc I can tell the real function).

Cheers,
