Union Server

Hi.
I got an unknown warning on server console.

What I did just run the server.
And then run the Admin application.
After a few seconds the server console shown a warning:

2009-06-09 11:24:06,015 WARN - No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: jar:file:/C:/union_a2/lib/ehcache.jar!/ehcache-failsafe.xml

This warning didn't came until some application connected to the server.
I noticed that this warning appeared only after 1st client connection.

Here is the server log:

I am using Union Alpha 2 with Reactor Alpha 2;
on Windows XP SP2; and Java Runtime 6 update 13.

I don't understand this warning; my application is running just fine.
Just thought I should report it.
