I agree that disabling IM completely on JPasswordField is the fundamental fix, but the current macOS can still activate the prediction candidate feature even if the target component doesn't accept non ASCII characters. Then, the feature may call native codes.

I'd like to prevent crash this time. Also, the other IM related native codes in AWTView.m have similar checks, and only attributedSubstringForProposedRange lacks them.
