Search bytecode for calls to System.exit

Question

I have a Java batch which is mysteriously calling System.exit.

Is there a way to statically analyse all bytecode in the classpath to see where calls to System.exit could come from?

I don't have access to the environment where the batch is run, so I can't easily modify the environment to trap this call.

Answer 1

I've found this:

If you use Unix/Linux:
Exit-code above 128 means that the process died because of a received
signal (exitCode = 128 + signalNumber).
==> In your case it was signal 9 (= SIGKILL).

here: Understanding error - Java returned: 137

So maybe someone killed your batch.
