is 4.11 still a good idea?

[Foo Ji-Haw]

Hi guys,

I'm thinking of installing 4.11 on my next server, seeing that we have 
some Java issues on the 5.x series (I've been informed that native Java 
on 5.x is not a good idea).

Can I get some feedback on whether development and/ or support on 4.11 
is still active and updated? I've spent quite some time on the 4.x 
series, so I am quite comfortable with it.

Thanks!
