No JAVA7 SE JSR up to now, but the proposed features include many attractive ones. Most notably,
1) Reified generics: really??????!!!!!!! So, .NET’s choice was the correct one in the beginning while Java failed? Never mind. Hope this dream come true!!!
2) Type literals: wow!!!!!!!!!!!!!!!!!!!!!!!!!!
3) Language level XML: expected for a long time.
4) JavaBean Property Support: it took so long.
5) Closures: finally!!!!!!!!!!!!!!
6) Miscellaneous – BigDecimal supporting arithmetic operators, String literal in case, and < and > operators for Enum

Amazing!!!
