The JDK has two mechanisms for introducing "experimental" features:
1. Preview features, which are new language or VM features that are
enabled by a command line switch
2. Incubator modules for new library code
Neither of those address adding API to an existing package / class in an
existing module, and it would be a fair bit of work to refactor it into
an incubator module, not to mention the work needed to deliver a new
module...

Hi,
This is good news but may I suggest we do something similar to OpenJDK
who also has explictly marked experimental/preview features shipping in
releases who can naturally get removed in a follow up release.
I would appreciate this in contrast to not getting this feature
integrated at all in FX-13.

The PR discussed in https://github.com/javafxports/openjdk-jfx/pull/472,
addressing https://bugs.openjdk.java.net/browse/JDK-8167148 provides a very
much wanted feature. It is important that things are done in the right way
so that the code can be maintained in the long-term future.
Therefore, feedback on this PR is extremely important before we can
consider merging it. Once this PR is merged, there is no easy way back. It
is possible to add more functionality, hence my preference is to only
implement the functionality that is safe and stable, while allowing other
functionality to be added later or by third-party extensions. (e.g.
(avoiding) copying from/to GPU)
To make it easier to give feedback, we've build early access versions of
SDK's including this PR. Note that the PR is not merged, hence not
available in the regular EA downloads!
If you want to give it a try, download the SDK's from the URL's below.
There is a test in tests/manual/graphics/PixelBufferPerformanceTest (
https://github.com/arapte/openjdk-jfx/blob/JDK-8167148-NIO-ByteBuffer/tests/manual/graphics/PixelBufferPerformanceTest.java)
that should get you started.
