How to lean (debug) javac

[Jonathan Gibbons]

Wei,

We recently reorganized the  source code and some of the documentation
still needs to be updated.

To fix the error regarding boot.java.home, create a file  
"build.properties"
in the langtools directory, and in that, define boot.java.home to the
version of java you wish to use to build the compiler.

Regarding the instuctions at (2), these are out of date following the  
reorganization.
The compiler can now be found under .../langtools/make/netbeans/compiler
