Hudson commented on AXIOM-377:
------------------------------
Integrated in ws-axiom-trunk #490 (See
[https://builds.apache.org/job/ws-axiom-trunk/490/])
AXIOM-377 (step 2): Reversed the DataHandler creation logic. In 1.2.12, the
DataHandler is created by PartOnFile/PartOnMemory, i.e. after the MIME part
content has been buffered. If we want to support streaming, then the
DataHandler must be created before we decide whether the content is streamed or
buffered and how it is buffered. Note that this implies that we now always
create a DataHandler implementing DataHandlerExt. For memory buffered parts,
the purgeDataSource method will simply release the allocated memory.
