             Summary: Weld crashes when attempting to read 
                 Key: WELD-1081
                 URL: https://issues.jboss.org/browse/WELD-1081
             Project: Weld
          Issue Type: Bug
          Components: Reflection layer
         Environment: Weld 1.1.6-SNAPSHOT, Groovy 1.8.6
            Reporter: Sam Corbett


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

{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}
