Splitting bug #652040 into smaller bugs.
jbr8? ( GPL-2 )
jbr11? ( GPL-2 )
However, looking into 'license/' directory in the tarball already proves this to be incomplete (why didn't even anyone bother doing that?!).
Created attachment 593280 [details]
I believe these are all the licenses specified in the license directory.
BSD-2 #json schema
custom-jdk? ( GPL-2 )
LGPL-2.1+ # Trove library
MIT # winp library
OROMATCHER #needs to be added
(the above is for the latest upstream version, 2019.2.3 which technically isn't in portage yet)
