Library Conflict Involving BCEL Library 2006-09-20 - By Eric Everman
Edwin -
This is a know issue and I have posted a bug for it back in Sept 05
(!). There is even a portion of the Ant build script that will build
the jar files w/o the inclusion of BCEL, but its not being used for
the released version.
Please, if you are reading this, please go to this bug entry and vote
for this bug:
https://issues.apache.org/jira/browse/XALANJ-2196
Thanks Much,
Eric Everman
