[OpenJDK 2D-Dev] Cleaner usage in java2 / awt

[Jim Graham]

We should probably be looking to replace Java2D's Disposer with the new 
Cleaner.  The reason that we didn't use the prior non-public Cleaner was 
that it didn't support all reference types and we were using (I think) 
Phantom references?  I think the new public Cleaner is more configurable 
so we should look into it again.

In the meantime, if the new Cleaner mechanism meets your needs then 
please do use it...
