Hi Ondra,

I think it is a different cause. The last issue was that the JDBC object store caches connections, this new issue seems to be related to there not being a dependency between the TM and JCA services (i.e. from a BZ point of view, this new issue could affect the initial load, not just a :reload)?

I will look further...

> The JDBC object store makes a performance optimization to cache the datasource it obtains connections from. Unfortunately this is not compatible with WildFly :reload (see linked bugzilla for stack trace).
> Without further performance constraints I have moved to obtaining a reference each time. If there are performance issues we might need to provide a way for the subsystem to invalidate the cached reference when :reload is called.
