Now that the JDK 7 developer preview is out, one might think that it's time for a new JLS. After all, there have been changes to the language, albeit small ones.
I haven't found anything yet. When will a new JLS will be available, and from whence will one be able to get it?
You might be interested in both of these:
JSR 901: Java Language Specification
JSR 924: Java Virtual Machine Specification
Not surprisingly, both of them have recent draft reviews...
