I've now made some investigations of jEdit history, using what looks like
a semi-official git mirror of its SVN:
It seems that in the past Slava Pestov has made many workarounds of the
key event model of various Java versions on different platforms, notably
in jEdit/org/gjt/sp/jedit/gui/KeyEventWorkaround.java. He was using both
very colorful language ("this is retarted", "this is crap"), and some
meaningless changelog entries like "foo" or "fixed bug". The last relevant

numeric keypad, hoping for the best. (We are in a slightly better

versions of Java, and we have just this one version that is bundled with
I had also tried to avoid KeyEventWorkaround.processKeyEvent in
