Perhaps you would like to take Brandon's test InflateIn_DeflateOut.java?

Aside from incompatibility, some users might want SYNC_FLUSH,
some might want FULL_FLUSH.  I think it's too big a change.
So just add a new method on DeflaterOutputStream to sync flush
current output.

I think others have tried and failed to change the behavior of
various isAvailable methods in the past.

Compatibility sucks, but users love it.

Given that you, Xueming are the current nominal owner of java.util.zip,
and we can't include both fixes in the JDK,
perhaps you would like to drive this, while getting input from us,
and being able to use anything from our fix?
