> To reproduce:
> 1. Download attached minimal WAR (as7-2077.war)
> 2. Deploy WAR to a fresh install of JBoss AS 6.0.0.Final. Hit http://localhost:8080/as7-2077. Should say 'success'
> 3. Deploy WAR to a fresh install of GlassFish 3.1. Hit http://localhost:8080/as7-2077. Should say 'success'
> 4. Deploy WAR to a fresh install of JBoss AS 7.0.0.Final. Deployment will fail
> The deployment error is:

> We understand the error. The new JBoss AS 7 classpath scanning code is looking for EE annotations (such as @Stateless) inside the WAR, but some of the JARs in the WAR have optional dependencies (ie. an optional dependency on Spring). 
> However we don't believe this should fail the deployment. It didn't fail on JBoss AS 6 and it doesn't fail on GlassFish 3.1.
> This issue is affecting other projects, such as Vaadin, not just Metawidget. For further discussion, see AS7-708.
