New Revision: 1480079

URL: http://svn.apache.org/r1480079
Log:
A sligthly modified patch from Christoph Neuroth for "Exceptions logged when 
caches contain collections with unserializable objects" 
https://issues.apache.org/jira/browse/OFBIZ-5184

jacopoc commited revision 1352575 which would prevent stack traces to be logged 
when viewing the cache overview screen in /webtools. However, a stacktrace is 
still logged when the caches contain collections which themselves contain 
objects which cannot be serialized.

jleroux: I simply used logWarning instead of info
