Description

The groovy.transform.EqualsAndHashCode AST transformation does not handle object graphs with cycles. See the attached junit tests.

Some of the test methods I included actually pass - I just included them for completeness. Basically, the equals method handles cycles just fine. The hashcode method does not so all the tests related to the hashcode method fail.

This is a pretty serious issue because these object structures are common with some frameworks (like orm tools)
