I ran spec. spec complain about tools_jar variable is nil.

I tries to find tools.jar on all of my install JDKs, but I can't.
I found Mac OS X JDK doesn't provides tools.jar. See http://developer.apple.com/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html#/
/apple_ref/doc/uid/TP40001884-SW1
Javac.compile should handle this case.
