Johannes Rudolph updated JBSEAM-4458:
-------------------------------------

    Attachment: jboss-el.patch
                jboss-el.jar


I manually patched jboss-el.jar to include some fixes. The better solution would be to upgrade el from the original Tomcat EL implementation, where the bug was fixed before, too. 

For now, you can use the version supplied. It is just the original sources with the given patch applied.

> The title says it all. Here's the Bug-Report in the apache bug tracker. It seems the JBoss-EL implementation was directly copied from there:

> The problem lies in ELArithmetic.isNumberType which - in the version integrated into JBoss EL - uses a stupid way to determine if an object is a Number.
