loader constraint violation in interface itable initialization: when resolving method "org.apache.batik.dom.AbstractDocument.createEvent(Ljava/lang/String;)Lorg/w3c/dom/events/Event;"

Hi,

I created a test case on https://demo.globalqss.com/webui/index.zul to reproduce the error as you can see below:

1 - fill the EAN field of product window ( 13 digits)
2 - click on "print unprocessing..." button

A simple label (jasper report) with a EAN13 barcode should be printed, but instead of that i got the error

:

Looking forward about that i got some related issues:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=421553
https://bugs.eclipse.org/bugs/show_bug.cgi?id=522740

I think that an jasperreports upgrade should solve the problem, but i'm in doubt on how's the better way to fix that in iDempiere.

this error could block some important jasper features for a production environment when migrating to 5.1 and forward.

WDYT ?
