Subject Re: NullPointerExceptions - ReplicationValve problem...
Date Thu, 26 Jun 2008 08:12:46 GMT
Unfortunately i don't have test case... Can you suggest me some way so i can
make test case, and give results back to you.

Interesting thing is that if filter parameter is empty for example:
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter="" />

i don't get any exceptions. In any other case null pointer exceptions occur.
