Description Tim deBoer

I've seen the following error in my .log several times today. I don't know what I was doing at the time, and am using last week's WTP 3.2.1 build (i.e. not the very latest, but I think it contains all Dali fixes).

Investigate for 2.3.2.

Unable to reproduce...retargeting.

Comment 3 Neil Hauge

Moving JPA specific bugs to new JPA component in bugzilla.

I'm closing this as unable to reproduce until a reproducable test case is provided. A lot has changed in the Juno release so this may have been fixed anyway.
