Description Petr Nejedly 2004-07-16 13:08:21 UTC 
ant/project issue
ByteOutoutStream defaults to 32B, vhich is way too
low for GFH. It causes several reallocations with
memcopies.
If the GFH knows future size (as in case of
reading a file into a byte array), it should tell
it to the BAOS constructor.
Comment 1 Jesse Glick 2004-07-16 21:22:00 UTC 
OK, I will use InputStream.available() as an estimate.

Comment 3 Petr Nejedly 2004-07-19 09:20:49 UTC 
OK.
I thought you'll use file size, but it seems that available()
returns correct value.
