David Lloyd commented on AS7-3796:
----------------------------------
The only way to definitively prove a leak is to execute a small number of invocations (say less than 10 at a time) repeatedly. If the exception is thrown, it's a leak, otherwise no.
Also, make *sure* your client is using the latest Remoting, XNIO, and EJB Client JARs.
