tar error unpacking Derby 10.1.1.0 gzipped libraries

[Rick Hillegas]

I downloaded the Derby 10.1.1.0 gzipped libraries 
(db-derby-10.1.1.0-lib.tar.gz 
<http://apache.mirror99.com/db/derby/db-derby-10.1.1.0/db-derby-10.1.1.0-lib.tar.gz>) 
and when I untarred the contents, tar complained "A lone zero block at 
14410". I didn't have any trouble downloading and unpacking the 
corresponding zip version (db-derby-10.1.1.0-lib.zip 
<http://apache.mirror99.com/db/derby/db-derby-10.1.1.0/db-derby-10.1.1.0-lib.zip>). 
I also had no trouble downloading and unpacking the gzipped 10.0.2.1 
libraries. I'm using cygwin on xp to unpack these distributions.
