[seam-issues] [JBoss JIRA] Commented: (JBSEAM-4552) AbstractMethodError thrown when attempting to invoke JPA 2 method on EntityManager

[Michael Youngstrom (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-4552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12515846#action_12515846 ] 

Michael Youngstrom commented on JBSEAM-4552:
--------------------------------------------

So, unfortunately since Seam is currently compiling against JPA 1 I cannot simply implement the missing methods without changing Seam to compile against JPA 2 which we probably don't want to do in a point release.

Is anyone against me rewriting the EntityManagerProxy code to use a Proxy instead of a concrete class?

> When I attempt to invoke a JPA 2 method on a Seam managed EntityManager I get an AbstractMethodError.  This is because org.jboss.seam.persistence.EntityManagerProxy doesn't implement any of the new JPA 2 methods.
> I believe if we're targeting 2.2.1 as something that will work in AS 6 we should fix this.
> I'll be committing a fix shortly unless someone stops me. :)
