Almost everyone eventually runs into GC issues with Java.

Is there a cookbook guide or semi-automated tool to tune GC for Java?

My rationale is this:

Almost anyone eventually has these problems
There are many possible factors (say 20) out of which only a few affect your problem.
Most people don’t know how to identify the key factors so GC tuning is more like a black art than a science.
Not everyone uses a HotSpot VM. Different Sun versions have different GC characteristics.
There is little incentive to experiment (like run the VM with slightly different settings every day to see how they play out).

So the question really is: Is there something that I can use in a check-list manner? Or maybe even a tool that analyzes GC logs or heap dumps and gives me specific hints where to look (instead of telling me “95% of the data is allocated in objects of the type byte[]” which is basically useless).
