I've seen this in practice (good or bad I don't know) when we needed to process
large amount of data and nullifying EC or replacing EC was not releasing the
memory consumed by original EC (monitored using JConsole), the call to
dispose() released the memory. What would be the reason then? Perhaps terribly
bad code or are there any strong references to EC?
