How does this file get the include for JVMFlag?   I don't see 
jvmFlag.hpp included anywhere but one cpp file.


Shouldn't this #include jvmFlag.hpp too?

I can't find anything that includes jvmFlag.hpp except jvmFlag.cpp but 
there are many files that have JVMFlag::Error in them.

This is a nice refactoring!
