Less logging for same WAR under Windows compared with Linux

[lthomps4]

If I deploy the same WAR file to Windows and Linux JBoss environments and execute steps that I know create an error; on Linux the stack trace is shown, on Windows the stack trace is not, yet the error is happening in both environments as shown in the application's web page.  The standalone.xml is the same for both environments.  How can I get my Windows environment to display the same stack-trace? Has anyone else come across this issue?

The below exception appears in Linux, but is suppressed in Windows. As far as I can see, all config is the same:

12-12-03 13:18:25,798 ERROR [yyy.ExceptionController] (http-syddev55-vip10/10.134.154.72:8443-6) org.hibernate.exception.GenericJDBCException: could not insert:

I was able to get the stack trace by removing log4j.properties and log4j.xml that were contained withing the WAR file. This doesn't explain why Linux was able to output trace but my issue is now resolved.
