Exception depth in log4j

Question

Im getting in instantiation exception inf our Myfaces 2 application. But the exception printing through log4j is cutting off the rest of the stacktrace. Here is what I am seeing:

I cannot find where to change the config so I can see the "... 48 more". Any ideas?

Answer 1

You cannot. The truncation of the stack trace is a feature of the JVM, not log4j.

It's actually only discarding information that it has already presented to you. The ... 48 more is a shorthand for the 48 frames that preceded the "Caused by" message. So, in your case, the elided 48 frames are:
