I still get them reliably. But, as I just realized, only when the
Isabelle/jEdit window is maximized.

Do you mean the regular maximize button, or the jEdit action
toggle-full-screen (F11)?
The regular maximize button.

Trying F11, I did get the exception once and then it showed up
continuously e.g. when resizing the window. This "exception" mode is not
realiable, though, it only happens sporadically.

Since it is repeatable for you: Can you try with the
Isabelle2019-RC2.exe desktop application and check the exception trace
in the activity log? See menu Utilities / Trouble Shooting / Activity Log.
Yes, I've attached the activity.log. Looks like the NPE always occurs together with [debug] EditBus: ViewUpdate[what=VIEW_ACTIVATED,source=org.gjt.sp.jedit.View[active]]
[debug] jEdit: checkBufferStatus for all buffers
[debug] EditBus: DynamicMenuChanged[menu=recent-files,source=null]
