the sdk seems to freeze for a short period and this error appear

When opening the file fails, the input stream is never closed and thus this 
error occurs. Close the input stream in a finally{} statement.

Yeah that's the first thing i did, but the issue still occur.
I guess it's a bit trickier than that...

mhhh wait i was just going 
niftyObject.getPrimaryFile().getInputStream().close();
getInputStream() returns a new input stream each time.
It seems to work now that i keep a reference on the stream.
