RFR(S) Remove excessive inclusion of arguments.hpp

[Ioi Lam]

Hi Thomas, thanks for the review.

Some cpp files use vm_exit_during_initialization(), which is defined in 
java.hpp, which was included by arguments.hpp.

Now that I have removed arguments.hpp (indirectly) from these cpp files, 
I have to add java.hpp to fix the missing dependency.

Thanks
- Ioi
