Yes, always lock.  I'd take it even one step further:

Ick! Public instance variables are an abomination. I hope that was typo...

image.setTitle(newTitleForImage);

Ah... that's better.  :-)


ec.saveChanges();


} finally {
    ec.unlock();

}

Better safe than deadlocked (unlikely in this case but possible if you keep the ec around and an exception is raised from saveChanges().

I've become paranoid about locking all editing contexts but the session's default editing context. Please correct me if I'm wrong to suggest the above in this situation.

Aloha,
