Hello Hyunik,

I am using revision 9178, which compiles fine for me (it should compile
with JDK6).

I've compiled OpenJDK 7 b146 "langtools" i.e. javac (the reference
implementation). I had to do some tweaking to get it to compile.
JastAddJ fails on some type checking with conditional expressions. I can
share my patches with you when I have time to compile them properly.

Oh yes I recognize this. It was an error in annotation processing of the
Override annotation in JastAddJ. I've fix this bug since a couple
revisions back (some week ago now).
