[jira] [Commented] (TAP5-2582) Service creation for Hibernate Session results in ClassFormatError: Duplicate method name&signature

["Hendrik Noot (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-2582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17067949#comment-17067949 ] 

Hendrik Noot commented on TAP5-2582:
------------------------------------

It seems that the root cause of problem was only partially fixed. It is fixed for service creation, but not for the creation of shadow proxies. The proxy is needed by the Hibernate module in HibernateCoreModule.java:118, as seen in the stack traces above and also this duplicate issue: TAP5-2597

This could be caused by PropertyShadowBuilderImpl.java, the PlasticClassTransformer code there looks quite similar to PlasticClassImpl and has not received any changes to keep methods unique. 

I created a test that reproduces the problem. I hope that submitting it as patch to an existing test class is ok.
