Juraj Huska commented on RF-11409:
----------------------------------

I have tried to reproduce this error with 4.1.0.20111011-M3 showcase, and I found that this error is logged to the console only when I am starting Tomcat *not with startup scripts*, which should set all variables but via calling specific jar files with specific flags, which is also done in Arquillian, to start Tomcat(I have written the plugin for Arquillian).

*In documentation for Tomcat is written:*
When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out.
Whatever is written to System.err/out will be caught into that file. That may include:

Uncaught exceptions printed by java.lang.ThreadGroup.uncaughtException(..)
Thread dumps, if you requested them via a system signal

So in case that there are logged all exceptions in catalina.out when starting Tomcat via startup scripts from CATALINA_HOME/bin, *then issue is not related to RichFaces* but it is problem of improper starting of Tomcat. Another clue for this is that in stacktrace exception there are only Tomcat relative classes.

> When push is done on all samples for aj4:push in showcase, then NullPointerException is thrown but the expected result of push is there. So the functionality is correct, only on the server console exception is thrown, with this stacktrace:
> {code}

> This exception is thrown after each push execution, and it is not broken after first trowing.
