Stefan Bodewig commented on COMPRESS-407:
-----------------------------------------
Have a look at
https://www.freebsd.org/cgi/man.cgi?query=tar&apropos=0&sektion=5&manpath=FreeBSD+7.0-RELEASE&arch=default&format=html
for the terminology we use. The record is the 512 byte entry, a block is a
batch of records.
With 1.15 we have changed the default block size to a single record - and not
documented that properly, it seems. You should be able to get back to the
behavior of 1.14 by using an explicit {{TarArchiveOutputStream}} constructor
with a block size of 10kB.
I'll try to make things more explicit in the docs.
