Variable initialization within closure?

[Kannan Goundan]

I'm not sure if this behavior is defined by the spec or a bug in the
"javac" prototype:

   int x;
   { =>
      x = 1;
      System.out.println(x);  // javac: variable x might not have been
initialized
   }.invoke();


I realize that 'x' shouldn't be considered definitely assigned after
the closure.  But it seems unintuitive that 'x' would not be
definitely assigned inside the closure as well.

(I compiled code from
"http://hg.openjdk.java.net/closures/closures/langtools" and ran
"dist/boostrap/bin/javac -source 1.7".)
