              I wasn't able to duplicate the class cast exception but this document has some shared object that are used on each pages and uses crypt filters. Definitely looking at some concurrency issue.

              Tightened up some locking on the StandardSecurityHandler as well the PcolorSpace class. This seems to have significantly reduced the occurrence of any empty byte[] after a stream has been decrypted and decoded. Applied patch to trunk and 5.0.1 branch.
