I'd bet you have not seen this exception more than once. Lucky moment to catch 
such race condition.

Double locking is bad: 
 
          if (method == null) { 
              try { 
!                 method = XMLDataObject.class.getDeclaredMethod 
("createInfoLookup", new Class[] { // NOI18N 
                      XMLDataObject.class, 
                      XMLDataObject.Info.class 
                  }); 
!                 method.setAccessible (true); 
              } catch (Exception ex) { 
                  ErrorManager.getDefault ().notify (ex); 
                  return null;

          // well, it is a wormhole, but just for default compatibility

              try {
