<div class="moz-cite-prefix">Jeff,<br>
<br>
the calls are there to cover cases when the creation of
RuntimeManager are not executed as part of an active
transaction since only then the transaction synchronization
is registered. I guess that in your case you are within
container manager transaction and thus tx synchronization is
registered which causes the behavior you described.<br>
I'll check that to ensure that the init method will not call
the dispose/destroy if it's within active transaction.<br>
<br>
Just for information as that might not be directly clear why
the init method creates session and the disposes/destroys it
- it is to ensure that start events will be properly
initialized - e.g. timer start event based processes will be
by that notified and executed according to definitions.<br>

<div>Hi.</div>
<div> I'm doing a deep dive into the new jbpm6
PerProcessInstanceRuntimeManager functionality.</div>
<div> Impressive.</div>
<div><br>
</div>
<div><br>
</div>
<div> One minor observation is that it seems that both
the engine.getKieSession().destroy(); and
disposeRuntimeEngine(engine); function calls in the <a
moz-do-not-send="true"

function are redundant.</div>
<div> Neither of these calls seem necessary.</div>
<div> Previous to these function calls, an instance of
DisposeSessionTransactionSynchronization() was already
registered .... which takes care of appropriately
disposing the session after the JTA transaction has
committed.</div>
<div> Subsequently, when either (or both) of these
redundant calls to close the session prior to the
transaction has committed, the following exception
occurs:</div>
<div><br>
</div>
<div>
<p><span style="font-size: small;"
data-mce-style="font-size: small;">java.lang.IllegalStateException:

</div>
<div>I'm testing in an EAP6.1 environment using JTA
transactions provided by the app server.</div>
<div>commenting out those apparently redundant function
calls does not seem to cause any other negative side
effects and the session is still closed by the
DisposeSessionTransactionSynchronization instance.</div>
