Hi Carl,
Maybe you’ve seen that the ClientSession class implements the Closeable interface, so it’s generally advisable to use a try-with-resources statement when creating new instances.
If that doesn’t help, you could tweak your registry settings, as e.g. suggested in [1].
Best, Christian

We are using XSLT and invoking Java methods to handle the things not easily managed in XSLT. Should we be closing sessions in Java classes or is this supposed to be handled by the JVM?
This is running under Windows Server 2016 , deployed using JBoss 7.3.9, with 16 GB ram, and 4 cores.
