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  about becoming a contributor. There
is a GitHub sandbox  that you can fork and use to prototype your fix
and eventually send a pull request when ready. See CONTRIBUTING.md 
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  to see if it has
already been filed. Otherwise, you can file a new bug .
