The finalize() method is deprecated in JDK9. See [Java 9 deprecated features](https://www.oracle.com/technetwork/java/javase/9-deprecated-features-3745636.html). And so the [PiscesRenderer.finalize()](https://github.com/openjdk/jfx/blob/71ca899fbfc74d825c29b20a778d6d9eb243f90f/modules/javafx.graphics/src/main/java/com/sun/pisces/PiscesRenderer.java#L439) and [AbstractSurface.finalize()](https://github.com/openjdk/jfx/blob/71ca899fbfc74d825c29b20a778d6d9eb243f90f/modules/javafx.graphics/src/main/java/com/sun/pisces/AbstractSurface.java#L100) method should be removed.
The change is, 1. Remove finalize method from PiscesRenderer and AbstractSurface classes. 2. Use [Disposer](https://github.com/openjdk/jfx/blob/71ca899fbfc74d825c29b20a778d6d9eb243f90f/modules/javafx.graphics/src/main/java/com/sun/prism/impl/Disposer.java#L48) class for cleanup instead of finalize(). For SW pipeline the cleanup is initiated in [here](https://github.com/openjdk/jfx/blob/71ca899fbfc74d825c29b20a778d6d9eb243f90f/modules/javafx.graphics/src/main/java/com/sun/javafx/tk/quantum/UploadingPainter.java#L195) in UploadingPainer.java. 3. Added new JNI methods to JPiscesRenderer.c and JAbstractSurface.c and removed the ones which were used previously with finalize() method. Verification: Verified that the newly added dispose() methods get invoked as required and no OOM occurs. 1. Create a sample program which adds and removes non 3D shapes and/or controls to stage in a loop. 2. Run the program using -Dprism.order=sw, -Dprism.verbose=true. (optional -Xmx50m) Expected Behavior: a. Maximum memory consumption after this change should reduce or remain same as that of before this change. b. No OOM should occur with this change or without this change. ------------- Commits: - 31df0ebc: 8235772: Remove use of deprecated finalize method from PiscesRenderer and AbstractSurface Changes: https://git.openjdk.java.net/jfx/pull/66/files Webrev: https://webrevs.openjdk.java.net/jfx/66/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8235772 Stats: 111 lines in 5 files changed: 40 ins; 52 del; 19 mod Patch: https://git.openjdk.java.net/jfx/pull/66.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/66/head:pull/66 PR: https://git.openjdk.java.net/jfx/pull/66
