The easiest thing to do to debug JavaFX is to use a prebuilt JDK 8+ and attach
the sources from the JDK to your IDE.
Then you can set break-points in the JavaFX source and debug it (i.e. you don't
need to checkout and build openjfx at all).
This works fine if all you want to do is step through the JavaFX source in the
context of debugging your application (I think from your question this is
actually what you want).
For instructions on how to do this with Intellij Idea, see
http://stackoverflow.com/questions/13407017/javafx-source-code-not-showing-in-intellij-idea.
I think something like e(fx)clipse will do this step for you automatically
(not sure about NetBeans).
There is really little difference between the openjfx code and the source
shipped with JDK 8.
When you download JDK 8 (from https://jdk8.java.net/download.html) you are
receiving a pre-built tagged snapshot of software built almost entirely from
the openjdk/openjfx codebase.
Of course, if you are actually developing and modifying the openjfx source,
then the above won't work because your modified openjfx source would get out of
sync with the binary JDK8 code. In this case, you would need to check-out the
openjfx source, make any modifications you want, build it and then when you run
your application, ensure that you run it against your custom openjfx build and
have the modified source attached to your application's IDE project (similar to
the instructions in the stackoverflow question I linked). JavaFX has both
native and Java components. Debugging through the native components as well as
the Java components is a more complex task.
Perhaps there is more information on debugging openjfx on the openjfx wiki:
https://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFX
But the wiki is currently offline, so I can't check it at the moment.

Subject: Building and using a debug build of openjfx as the default JavaFX for
development
Hi everyone,
I've successfully built openjfx. My overall goal is to be able to step through
the openjfx code. I have the Oracle JDK installed - do I need to use OpenJDK
instead? How would I go about making sure the build produced has debug
information and using it for javafx application development. I'm trying to make
my way through this process but I don't have all the pieces put together yet,
and I'd appreciate any tips that can be offered.
Thanks!
Kay
