Adopt a JSR, a JUG initiative for you. Yes, you!
By alexismp on Dec 01, 2011
Adopt-a-JSR is a recent initiative by multiple JUGs (I believe the ever-active LJC started this) to encourage community participation in the JCP and more specifically in making concrete progress in developing new JSRs.
Some of that is a consequence of the JSR 348/JCP.next increased transparency and early results are very encouraging with serious progress made on the JSR-310 TCK for instance. A recently-added grid should provide and idea of the community and JUG efforts on specific JSRs.
As the program page on java.net says - "It looks great on the CV". In fact I think that resume-wise nothing beats serious contributions to industry-wide standards or open source projects and that's probably true around the world.
