I have an application that is using OpenJMS in RMI mode - I have
multiple PingThreads running in the background and I was wondering if
it was because I was not closing the publishers/subscribers correctly
(TopicPublisher.close).

I noticed that there is a way not to have these threads by specifying
clientPingInterval="0" in the openjms.xml file, but what is the use of
these threads?
