Please let me know how I can fix this. Thanks!
Unfortunately, this project hasn't been maintained in a while and I personally have no idea what's going on here. I haven't touched this code in years. @SamCarlberg any thoughts?
Same here. From the stacktrace, it looks like the mac runtime wants to read some attribute from the language combobox, but something internal there is hitting a NPE. Maybe it's a bug in JavaFX on macOS; there's nothing we can really do about there
A few years ago there was a javafx bug that was broken on newer releases of macos. There was a fix released in newer versions of javafx, but that would require updating which is unlikely to occur.
https://bugs.openjdk.org/browse/JDK-8184270
Seems like it was fixed? But only in java 10? https://hg.openjdk.org/openjfx/10-dev/rt/rev/b29e458bb99c
@iyeravyukt Looks like you're running into this javafx bug: https://bugs.openjdk.org/browse/JDK-8184270
As Jonathan said, GRIP isn't actively maintained any more. Using GRIP on a different operating system (windows, linux) should avoid this issue.
