We've been using the OpenSessionInViewFilter for months now without much
incident at all (aside from the usual carelessness that comes with
closing and opening sessions around HTTP Requests). Lately though,
there's been this error that happens when I save a collection of
entities and try to reload them. The errors below happen when the
application hangs and I have to shut down the Jetty web server. It
hangs after the opening JDBC connection line:

Anyone know what to do about this? I'll probably go to the Hibernate
forums with it too, but I wanted to start here. I could upgrade to the
latest Spring too just to cover my bases...
Many thanks,
