-----------------------------------------------------------

After reviewing the regresssion in the above BZ, it looks like it was actually caused by the use of the wrong {{TransformerFactoryImpl}}.  See: https://bugzilla.redhat.com/show_bug.cgi?id=1087993.

It actually looks like this patch was never pulled in to EAP at all.  With that in mind, can you look into merging this fix into WF again?

> It has been observed that when using the {{Transfomer}} to convert a {{StreamSource}} to {{DOMResult}}, the performance of Transform gets worse as the size of the
> character data increases.  If you have a 50MB text blob in XML, this will take a very long time to finish.
