Description

After an unspecified amount of time, usually less than twelve hours, a thread repeatedly deserializing SOAP calls will eventually throw a java.lang.OutOfMemoryError. For instance:
Exception in thread "Thread-2" java.lang.OutOfMemoryError: Java heap space

It is worth noting that the thread in question maintains very little state itself. It pulls objects from a queue, makes a soap call with that object as a parameter, and then puts the result in another queue. That is all that is expected of that thread.

This is either very similar or identical to the problem reported for version 1.2 reported here but unassigned: https://issues.apache.org/jira/browse/AXIS-2698

I wanted to make sure this was also identified as a 1.4 problem. This bug is making the Axis library incredibly unstable for me.
