A DESCRIPTION OF THE PROBLEM :
The crimson XML parser is choking on valid XML. Its a
problem to do with ]]> characters spanning the 8K parsing
buffer.

The following URLs include a test case and patch to resolve
the problem:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4947
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5089

This wasn't a problem in the pre 1.4.1 release because I
don't think crimson was included in those releases.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.lang.InternalError: fillbuf
