Can JIT be enabled on jdk-6?

[Fernando Seiti Furusato]

Hello.

I work with porting on ppc64le and I am looking for some info regarding
enabling JIT on openjdk-6.
I am sure it is not a simple task, but I have to ask :)
If anyone could help me out with this I would appreciate.
These are the initial quetions I have:

1 - Is it possible to do a "backport" of what has been done on openjdk-7?
2 - How long do you think one would take to do that work of enabling JIT on 
openjdk-6, in case it is possible?

Thanks in advance.
