svn commit: r240366 - /portals/jetspeed-2/trunk/content-server/src/java/org/apache/jetspeed/contentserver/ContentLocatingResponseWrapper.java

New Revision: 240366

URL: http://svn.apache.org/viewcvs?rev=240366&view=rev
Log:
Temporary workaround handling IllegalStateExceptions thrown all the time on WebSphere.
As result, hardly any content (css, images) comes through.
This still doesn't make that working fully again, but at least with IE 6.0 it improves a lot.
With Firefox, the end result is still very bad (but somewhat improved nonetheless).
