Parallel Camera in Java 9+

[Kevin Rushforth]

I thought your question was about a replacement for copying a jar file 
into $JAVA_HOME/lib/ext (which also touches the JDK).

If you are interested in fixing a bug or otherwise improving JavaFX, 
then please see the OpenJDK page [1] about becoming a contributor. There 
is a GitHub sandbox [2] that you can fork and use to prototype your fix 
and eventually send a pull request when ready. See CONTRIBUTING.md [3] 
if you are interesting in contributing using the GitHub sandbox.

There are a couple of known bugs in ParallelCamera when working with 3D 
objects, so you might check the bug database [4] to see if it has 
already been filed. Otherwise, you can file a new bug [5].
