My Java application hang - how to investigate reasons of that?
Posted on 2010-11-14
I have written some Java application (on PC), packaged it to JAR and started. But after some time it hang. According to a log files I can see that sometimes it happens after ArrayOutOfBounds exception.
My question is - what the usual/recommended ways to investigate and solve such issues?
I mean - what the usual/recommended Java debugging practices?
Is it possible to attach Java process with debugger and check stack, treads, variables and so on?
Run a debug session from Eclipse is not working in my case because my Java application has a specific model which (seems) could not be debugged from Eclipse.
So, yes, I'm writing code in Eclipse but cannot use it as debugger because some things do not work under the Eclipse debugger.
That is why I need something alike to attaching a running Java process with Java debugger and investigate it.
Is it possible at all? What tools/approaches could you could recommend?
