Thanks. I took a quick look at it the other day and I think I know what
the problem is.

Hi Anton,
Can you file a bug in JBS? We can take a look at it, although it
might be difficult without a test case.

It seems to be caused by this fix:
https://hg.openjdk.java.net/openjfx/11/rt/rev/808d535c4e15
The "characterIndexForPoint" method performs "invokeAndWait" from
JavaFX thread:
LWCToolkit.invokeAndWait(new Runnable() {
public void run() { synchronized(offsetInfo) {
offsetInfo[0] =
fIMContext.getLocationOffset(screenX, screenY);
insertPositionOffset[0] =
fIMContext.getInsertPositionOffset();
}}
}, fAwtFocussedComponent);
which is then on EDT delegates back to JavaFX thread and waits for
async result.
Is it a known issue? Unfortunately, I can't give you a simple case
to reproduce it. Hope the problem looks clear from the description.
With best regards,
Anton.
