Joerg Schaible resolved XSTR-596.
---------------------------------
Resolution: Fixed
Fix Version/s: 1.x Maintenance
XStream 1.3.3 never existed, so I think this report was for XStream 1.3.1.
However, that was the first version that actually had a check for the
availability of the Subject class in the XStream initialization. Unfortunately
this check did only load the class, but without initializing it. Therefore the
converter was registered nevertheless and the runtime initialized the class
later at first access which caused the exception. XStream will now initialize
the class directly at loading time and ignore any occurring LinkageError
resulting in a normal failed attempt to locate it.
