Command completion fails when value starts with escape character: org.jline.reader.EOFError

[offbynull]

When terminal is created with a default parser and eofOnEscapedNewLine is set to true, tab completion on value that starts with '' will fail to EOFError exception.

Terminal terminal = TerminalBuilder.builder().build();

Completer completer = new StringsCompleter("foo", "bar", "baz");

DefaultParser parser = new DefaultParser();
parser.setEofOnEscapedNewLine(true);

LineReader reader = LineReaderBuilder.builder()
        .terminal(terminal)
        .completer(completer)
        .parser(parser)
        .build();

while (true) {
    String line = null;
    try {
        line = reader.readLine("prompt >", null, (MaskingCallback) null, null);
    } catch (UserInterruptException e) {
        // Ignore
    } catch (EndOfFileException e) {
        return;
    }

    if (line == null) {
        continue;
    }

    line = line.trim();

    terminal.writer().println(line);
}
