And the problem is still there! Why don't you fix it?

@fablau has now submitted an issue report for this bug (thanks!):https://github.com/arduino/Arduino/issues/10219
I tried to create a copy of the IDE (with Teensy stuff) with a slightly newer OpenJDK version.https://www.pjrc.com/teensy/td_152/Teensyduino_MacOS_Catalina_Java8u252.zipPlease give this a try and let me know if it helps? I really want to find a solution for this bug (not requiring 1.8.10) but my Macbook Air with Catalina doesn't reproduce the problem, so I'm depending on your feedback.
I am seeing the crash any time I click a scroll bar. In a setting screen or in the text editor. I am on 10.15.5 Beta (19F83c)
To everyone: about the problem on Catalina 10.15.5 Beta window scrolling issue mentioned earlier, it looks like the latest version of Catalina beta (19F94a) fixed the problem. At least for me.
