[jira] Commented: (OPENEJB-750) EJB 2 Entity bean with many to one relationship causes ClassFormatError

["Jonathan Gallimore (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENEJB-750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12563326#action_12563326 ] 

Jonathan Gallimore commented on OPENEJB-750:
--------------------------------------------

This also appears to happen when deploying the EJB-JAR from the Geronimo Bank sample (from v1.2), so I guess this isn't down to an error with my sample app.

> When deploying a CMP entity bean which has a many to one relationship, the following stack trace is produced when a class that is generated on the fly is loaded.
> This appears to be because the getter/setter for the field that links the entity to the parent is generated twice with the same signature - once as a regular CMP field, and once as a field that is participating in a CMR relationship.
