(That comment is a note to myself about where/why in NB there is an NPE)
What version of JavaFX are you debugging?
That is code inside of NB. It seems like NB is looking for something,
com.sun.javafx.runtime.SystemProperties, that does not exist in the javafx
that you are debugging.

I'm so sorry for the late reply.
I completely ignored it and forgot about this issue.
However, please explain. I don't understand your code at all.

In "setFxDebug" there is
{code:java}
ClassType sysPropClass = getClass(vm, tr,
"com.sun.javafx.runtime.SystemProperties");
{code}
but that class doesn't appear in openjfx (AFAICT). So this leads to a NPE. Can
probably just return or check that in fact this is openjfx.

Below is the comment and some code for the method
org.netbeans.modules.debugger.jpda.visual.VisualDebuggerListener.setFxDebug
which catches and reports the exception.
Note that exceptions are expected. Not sure why the stacktrace is output which
in turn causes NetBeans to bring up a dialog.
{code:java}
/**
* JavaFX runtime is boobietrapped with various checks for {@linkplain
com.sun.javafx.runtime.SystemProperties#isDebug() }
* which lead to spurious NPEs. Need to make it happy and force the runtime
into debug mode
*/
private static void setFxDebug(VirtualMachine vm, ThreadReference tr) {
...
} catch (Exception ex) {
Exceptions.printStackTrace(ex);
