Ales Justin commented on WELD-1081:
-----------------------------------

I don't really see what we (Weld) can/should do. Any idea?

> The Groovy compiler generates invalid class names for classes representing a Groovy closure inside an inner class (see [GROOVY-5351|http://jira.codehaus.org/browse/GROOVY-5351]).  This bug causes Weld to crash when calling WeldClassImpl.isAnonymousClass().  While Weld can't help Groovy's behaviour, it shouldn't crash either.
> The classes we have that cause this are:
> {code}
> brooklyn.event.adapter.JmxNotificationAdapter$_NotificationPushHelper_closure1
> brooklyn.entity.basic.MethodEffector$_AnnotationsOnMethod_closure2
> brooklyn.entity.basic.MethodEffector$_AnnotationsOnMethod_closure1
> {code}
> The exception that crashes Weld is:
> {code}
> Caused by: java.lang.InternalError: Malformed class name
> 	at java.lang.Class.getSimpleName(Class.java:1133) [:1.6.0_29]
> 	at java.lang.Class.isAnonymousClass(Class.java:1188) [:1.6.0_29]
> 	at org.jboss.weld.introspector.jlr.WeldClassImpl.isAnonymousClass(WeldClassImpl.java:386)

> 	at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1765)
> 	... 4 more
> {code}
> The attached project demonstrates the problem by having Weld load the following class:
> {code}
> public class ClosureClassNameTest {
>     private static class Inner {
>         def _ = [1, 2, 3].each {}
>     }
> }
> {code}
