Hi,
sun.misc.Cleaner has been moved to internal package jdk.internal.ref
recently [1] to clean-up sun.misc namespace. But now that:
- we have comparable public API (java.lang.ref.Cleaner & Cleanable) [2]
- we have an internal shared java.lang.ref.Cleaner instance
(jdk.internal.ref.CleanerFactory.cleaner())
- sun.misc.Cleaner is not a special kind of Reference any more in the
JVM [3]
...I think there's no reason to keep this special internal API any more.
It can be replaced with public API.
I propose to remove jdk.internal.ref.Cleaner class and replace its
usages with java.lang.ref.Cleaner and friends [4].
What do you say?
Regards, Peter
