             Summary: getMetaClass should be annotated as (JavaBeans) transient
                 Key: GROOVY-8284
                 URL: https://issues.apache.org/jira/browse/GROOVY-8284
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.4.12
            Reporter: Michael Lipp

All groovy classes have the "getMetaClass()" method. This breaks the (e.g. XML) 
serialization of groovy classes that are supposed to represent JavaBeans.

While the serialization provided with Serializable or Externalizable examines 
the attributes of a class, the special JavaBeans serialization provided by 
serializers based on 
relies on the information provided by the 

With respect to persistence, the PropertyDescriptor for "getMetaClass" should 
have the attribute value "transient" set. The Introspector generates this value 
if the method has been annotated as 
 Because this value is currently missing, the Encoder tries to serialize the 
MetaClass information, which fails.

The groovy compiler should therefore annotate the "getMetaClass" method with 
the runtime annotation "java.beans.Transient".
