There appears to be some problems when MetricsEnabled is set to true:
First :
The J2eeDeployer needs to be dependent on the SpyderMQ service, so I changed
the J2eeDeployer's depenency to :
<service name="J2eeDeployer">
<dependency service="EmbeddedTomcat" required="false"/>
<dependency service="ContainerFactory" required="true"/>
<dependency service="SpyderMQ" required="true"/>
</service>
Second :
When I try and run with metrics turn on, I keep getting an exception in the
container, stack dump below :
Line 152 is where the Transaction.HashCode is tried to be added to the
message, however this happends even when the EJB is in a transaction.

You got it.
And the same mechanism can be used in txmanager, caches, jaws, etc.
