question about Java

[Michael Butash]

Oh, you probably need commercial repos in ubuntu now.  Oracle (anything) is

as oracle jre 9 wants cash to use it from developers.  Which only hastens
its death unless that's all a developer knows.  Everyone in India learns it
as a second language since 1999, it's the only reason it still exists.
