I hope everything will be ok. Regarding the above problem, it's
solved: I moved message.get*Content outside the wile loop so I will
keep only one reference and read from that stream. I also used a
BufferedInputStream to speed up thing.
Unfortunately, save is not done yet. It seems to use a lot of memory.
If I eliminate save() by returning SimpleMessageMetadate from the
start, the test is green so the problem lies here.
I will keep you posted. Good luck with the recovery process.
Bye,
