How to build java vm in mixed mode instead of interpreter mode

[Srinivasa Rao Ragolu]

Hi Andrew,

I have been trying openjdk 8 recipe patches provided by Guy, yocto
developer. He takes source from aarch32-port and enables vm as client.

I have also tried images you uploaded and they are working perfectly fine.

Now I am facing one compilation error while building

error: comparison between signed and unsigned integer expressions
[-Werror=sign-compare]

Please help me how could I resolve this issue.

Thanks,
Srinivas.
