EL implementation doesn't coerce custom Number subclasses
---------------------------------------------------------

                 Key: JBSEAM-4458
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4458
             Project: Seam
          Issue Type: Bug
          Components: EL
    Affects Versions: 2.1.2.GA
            Reporter: Johannes Rudolph
            Priority: Minor

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:

https://issues.apache.org/bugzilla/show_bug.cgi?id=44766

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.
