It might seem ad-hoc but the InputMethod event design in mac is such that (which has been there from beginning of macport days) that we need to fix in this way as far I can tell (it has been fixed like this earlier also without any regression).
 The https://github.com/openjdk/jdk/blame/master/src/java.desktop/macosx/native/libawt_lwawt/awt/AWTView.m#L946 statement seems to suggest that as well, in my opinion, to send Input method event if we get such insertText "out of the blue!"
