Freeman Fang commented on SMXCOMP-666:
--------------------------------------
Hi,
This is a known issue for a input stream which isn't re-readable but you try to
consume the stream twice, so when you consume the input stream the second time,
you get the exception like "Attempted read on closed stream."
When you set the log at 'DEBUG' level, actually the input stream will be
changed to re-readable first underlying, in order to print out the stream
content but you still can read the content again, that's why it's working with
log at 'DEBUG' level.
So the solution could be change the stream to re-readable.
