[THREDDS #XIM-229931]: error 500 for WMS service in THREDDS

Hi Frederic,

Very interesting. I'm glad you got it working. Let us know if you investigate 
further and find out anything interesting.

Something we've run into in the past is deploying a new version over an old 
version without first undeploying the old version. I tend to use the Tomcat 
manager to deploy and if you don't undeploy first the new war is unpacked over 
the top of the old content in ${TOMCAT_HOME}/webapps/thredds. The undeploy 
removes the entire thredds/ directory so you get a clean install. We now make 
sure to undeploy first because of occasions when we saw strange, hard to trace 
class/version collisions when we didn't undeploy first.
