Hi Werner, We worked on it since my last email. So the problem is the Map _xmlNameMap in class XMLClassDescriptorResolverImpl that is not accessed in a safe thread way. We were unable to write a test program but we always had the problem on our business program: it make many heavy marshalling.
We discovered that your Revision 8186 : Added thread safety-ness to XMLClassDescriptorResolverImpl.DescriptorCacheImpl (CASTOR-2019)* fix our problem*. This CASTOR-2019 task is pending, so my question is: do you have something to complete to close it? And when do you plan to release 1.3.1? Thank you very much. 2009/11/13 Werner Guttmann <[email protected]> > Hi Sebastian, > > Sebastien Devolder wrote: > > Hi, > > > > I have a bug on a program running on IBM platform: AIX + IBM J9 VM (build > > 2.4) + Castor 1.3 > > > > Unfortunately, I cannot repeat the problem on my development workstation: > > Windows XP + sun jdk1.6 + Castor 1.3. > > > > > > 1.
