Like I said, you start by finding a suitable home for the code in an
Once you have that, you can begin the process to bring the necessary
code over into that new home.
Once you have done that, you can begin to adjust the code to whichever
JDK Project you're targeting. If you're targeting JDK 9, for example,
that means setting up a JDK 9 clone, adjusting the code accordingly, etc.
Once you have done that, you can start to separate the changes into
different buckets - for example, bug fixes or simple performance
enhancements might be easier to review and accept upstream than
algorithmic improvements - I'd guess.
Once you have done that, your next goal should be to find the simplest
possible change that you can get upstream from that Project, and then
try to make it move upstream to familiarize yourself with the process
and to socialize the planned changes.
It can be helpful to order the changes you want to make from simplest
and smallest to largest, and then proceed accordingly, in order to get
an idea of how much work it is to get a change of what complexity
socialized, reviewed and integrated. 
Once you have done that, you might find that there is enough left over
to draft a JEP, or two. Excellent, then go and draft a JEP, or two. At
that point you will have a much better idea of what it takes whom to get
your desired changes in what form into what release than when you
started out. In addition, the reviewers will have a much better idea
what to expect and plan for.
 A neat post from a Linux kernel maintainer on the need to spend time
to explore and socialize contributions in order to avoid rejection is
