openxml filter memory leak when batch processing cancelled...

[Former user]

Original issue 420 created by @ysavourel on 2014-10-07T17:47:48.000Z:

The openxml filter launches threads that feed piped streams. When the main filter crashes or is closed unexpectedly from the caller every document leaks 1meg+. On large batches gigabytes of memory can be consumed and not released until the jvm is closed.

total refactor of openxml filter. But there is still the issue of caching large numbers of xml events.
