Looking at
http://statistics.netbeans.org/exceptions/messageslog?id=577579
one can find:

we should not have two modules providing Xerces in the system:
[org.netbeans.libs.xerces] and ModuleCL@aede59e[org.apache.xerces_2_11_0]
Comment 3 Jaroslav Tulach 2012-05-18 09:59:04 UTC 
My guess is that the org.apache.xerces is coming from 

dougmcneild.name.xslt.debugger.container [1.4.1 1 120331]
dougmcneil.name.xslt.debugger [1.5.2 2 120331]

as it has the same impl version 120331. Stop using dogmcneil debugger for now.
