maeste: it looks like a bug on our side, can you raise a Jira for us please (maybe with your stack trace)?
<tomjenkinson> maeste: thanks for fixing WFLY-1460
<jbossbot> jira WFLY-1460 WildFly server fails to start with transactions configured to be run with JDBCObject store [Open (Unresolved) Bug, Major, Stefano Maestri] https://issues.jboss.org/browse/WFLY-1460
<tomjenkinson> maeste: it looks like the same thread is not used more than once?
<tomjenkinson> maeste: the connection was being held on the thread you see
<tomjenkinson> maeste: I assume that new threads are created constantly and not recycled now in WildFly?
<maeste> tomjenkinson: yup should be
<tomjenkinson> maeste: if there was a thread pool you would not have seen this
<maeste> tomjenkinson: hmmm is on shotdown
<maeste> tomjenkinson: on thread pool removing so
<maeste> tomjenkinson: BTW I've just configure jdbcstore No operation executed, and so I suppose no write on DB, and I get this stacktrace when I shutdown WildFly
<tomjenkinson> maeste: we can close the connections more timely it is ok, I don't know what the performance impact of connection.close with each object store update though
<tomjenkinson> maeste: when you say "this stacktrace" you mean the gist you pasted before?
<maeste> tomjenkinson: can't you close connection on shutdown? Well I'm fine to call a new convenient method on service shutdown if it's doable
<maeste> tomjenkinson: yup
<tomjenkinson> maeste: we are allocating one connection per thread

• clebert (~clebert@redhat/jboss/clebert) has joined #jbossts
  <tomjenkinson> maeste: would shutdown be called on the transaction manager before LeakConnectionDetecter is triggered?
  <tomjenkinson> maeste: if so that sounds like the best idea
  <maeste> tomjenkinson: yup
• Jaikiran (~jaikiran@redhat/jboss/Jaikiran) has joined #jbossts
  <tomjenkinson> maeste: ok, so we can do that, we can store the references that each thread creates in a global map too, then in shutdown close them all
  <tomjenkinson> maeste: then hook that into the transaction subsystem
