Hello!
I decided to move to Eclipse Juno because it can redeploy my web maven project quickly on save. And it is working well.
Unfortunately there is one bad thing:
Eclipse redeploys my webapp and error with EntityManager arises
- NullPointerException - because it was not injected.
Then I try to remove the error click to save and as a result I always have the error:
Caused by: java.lang.IllegalStateException: Attempting to execute an operation on a closed EntityManagerFactory.

I found on the Internet that this is a bug of eclipse juno.
I use the latest version 1.5.1.20120917.
Is there any workaround for this?
Thank you!
