I was just happily playing around with the settings on a few of my @Entities and now I get this error when I try to restart Tomcat. I've tried rolling back my code to when it worked, but I can't get this error to go away. Here is the error in the Tomecat log (it ocurrs just after processing the PersistenceUnitInfo). I'll post more upon request to save space. Any help please.

Fixed it! And I don't know how !

I've spent all day trying everything from deleting entities to rebuilding the
whole project from the ground up. I finally got it when I copied over a copy
of my pom.xml I had luckly saved on a thumb drive and did a mvn
eclipse:eclipse on my project. And now it works! There is no difference
between the two poms and I'd tried rebuilding the old pom and I hadn't made a
change to the old one in ages ... I think I'll spend tomorrow (Friday 13) in
bed .

I believe that missing class is part of Doug Lea's concurrency API, if I were you, I would start here:

What version of Tomcat are you using? In my personal experience there are a lot of "weird" problems with JPA on anything below 5.5.20 -- especially if you're deploying from within Eclipse.
