CUSTOMER SUBMITTED WORKAROUND :
Revert the patch. (But where's the corresponding removeObserver, and why is addObserver called on every call to setInputMethod?)

FREQUENCY : always
Comments
Fix request (15u). I would like to backport the fix to jdk15u for parity with jdk11u. The original patch applied cleanly.

Fix Request This problem was introduced in 11.0.10. 11.0.9 works fine as expected. It's regression issue for JDK-8254070. On Mac Catalina, if Input Source is changed, Java is crashed. The patch applied cleanly to 11u-dev and I verified this issue was gone. 11-bp label was there, so it may be OK. But I'd like to request jdk11u-critical-request just in case.

The issue is reported with JDK 16 ea build having JDK-8248532 fix. From the description, it appears that post applying the patch, the crash occurs as it attempts to call a method selector on a class for an instance method (- keyboardInputSourceChanged).
