Most things are working with either mode (JDK 10 with qualified exports
or JDK 11 without), although I do get a few test failures.
There is a serious issue with leakage into the public API that needs to
be addressed before worrying about the failures, but I'll list the test
failures at the end.
SwingNode.java:
This public class is part of the API. You cannot make any of the
following fields public as this would leak implementation into public API:
+ public int swingPrefWidth;
+ public int swingPrefHeight;
+ public int swingMaxWidth;
+ public int swingMaxHeight;
+ public int swingMinWidth;
+ public int swingMinHeight;
+ public final Object getLightweightFrame() { return lwFrame; }
+ public final ReentrantLock paintLock = new ReentrantLock();
+ public boolean grabbed; // lwframe initiated grab
+ public void setImageBuffer(...)
+ public void setImageBounds(...);
+ public void repaintDirtyRegion(...)
+ public void ungrabFocus(boolean postUngrabEvent)
If you need to access them from other packages, you can either use the
accessor pattern (this might be easiest) or else refactor it further to
move more of this down to the implementation. I note that even though
SwingNodeInterop is abstract, it can still have non-abstract methods if
that helps in your refactoring.
SwingFXUtils.java
Same problem as SwingNode, although to a lesser extent. The following
must not be public:
+ public static void runOnFxThread(Runnable runnable)
+ public static void runOnEDT(final Runnable r)
+ public static void runOnEDTAndWait(Object nestedLoopKey, Runnable r)
+ public static void leaveFXNestedLoop(Object nestedLoopKey)
JFXPanel is fine.

Two of these, SwingNodeJDialogTest.testNodeRemovalAfterShow and
SwingNodeJDialogTest.testStageCloseAfterShow, also fail on Mac
