[hibernate-dev] what's going on jboss.org???

[Elhanan Maayan]

no getting multiple resource message, but exactly the warnings he
http://www.jboss.org/feeds/post/transaction_timeouts_and_ejb3_jpa was
getting, ("invoked while multiple threads active within..") but i have no
idea why it's aborting the transaction, maybe because the 2nd getConnection
takes somewhat longer (don't know why, this could be the real problem,)
