Jacques Le Roux commented on OFBIZ-10133:
-----------------------------------------
Thanks Wai,
Your slightly modified patch is in
trunk r1821036
R17.12 r1821037
R16.11 r1821038 (conflicts handled by hand)
I just removed final for bufferSize, I see no needs for that local variable and
it can even be interesting to change its value externally at some point.
I did not close yet because, I already wondered about that, and after commiting
and fixing a conflicts handled by hand in R16.11 and I remembered this question
I forgot to ask: why you did not use length at all (previously used to set the
size of buffer). And if you have a good reason, then why did you not refactor
the method and remove the variable length which is now useless.
It seems to me that it should still be used, I see no reason to read empty data
in the buffer...
