Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Enterprise Application Platform 6.1.0 changed (compared to Enterprise Application Platform 6.0.x) the type of exception generated when a class is not on classloader classpath. As a consequence, application deployment would fail on Enterprise Application Platform 6.1. This has been fixed by changing the handling of java.lang.LinkageError instead of java.lang.ClassNotFoundException and java.lang.NoClassDefFoundError. As a result, application deployment works fine.

Description Marek Schmidt 2013-05-09 08:50:01 UTC

Description of problem:

In several places where Seam catches ClassNotFoundException, NoClassDefFoundError, ... it doesn't catch the general LinkageError, causing some deployments to fail on EAP 6.1 (those with Seam Remoting not bundling an an optional gwt-servlet)

Version-Release number of selected component (if applicable):
WFK 2.2.0

How reproducible:
Always

Steps to Reproduce:
1. Attempt to deploy seambay example to EAP 6.1

Notice the warning of failing to load components.xml because of the LinkageError exception, causing the deployment failure:
