Keymap.getDefault() method get a empty inputstream problem.

public static Keymap getDefault() {
InputStream inputrc = null;
try {
inputrc = Keymap.class.getResourceAsStream("inputrc");
} finally {
if (inputrc != null) {
try {
inputrc.close();
} catch (IOException e) {
// ignore
}
}
}

return new Keymap(inputrc); // this line get a closed inputstream, this may cause keymap initializing failed.
}

Just like the comment, using example/readline can reproduce it.

The affected entry point is Keymap.getDefault(); start there and reproduce the problem with example/readline. Check keymap initialization using the inputrc resource, then confirm that the example/readline path completes without the reported initialization failure.
