Hi Klaus,

We are aware that a proper resource management is an indispensable feature for any framework which is targeted to a Java EE container. But please consider that the Lightstreamer Java SE Client API has been primarily designed having in mind the client side environment, as almost prevalent use case for the majority of our end users.

All that said, we have already noticed the issue you reported, and I confirm that we are currently fixing it in the new version of the Unified API library, in order to make it perfectly working also on a server side environment, at least for what concerns a properly binding of the LightstreamerClient lifecycle to the one of a Java EE Session.

The new version of the library should be available within a week or two. We will post back here to let you know the availability on Maven.

Thanks and Regards,
Gianluca
