Description

This simple test is failing (I have groovy-all on classpath):

import groovyjarjarantlr.*;
import java.io.*;
import org.codehaus.groovy.antlr.parser.GroovyLexer;
public class Main {
    public static void main(String[] args) throws TokenStreamException {
        String exp = "println 4 / 2 + 3";
        InputStream inputStream = new ByteArrayInputStream(exp.getBytes());
        GroovyLexer lexer = new GroovyLexer(inputStream);
        while (true) {
            Token token = lexer.nextToken();
            if (token.getType() == Token.EOF_TYPE) return;
            System.out.println("token = " + token);
        }
    }
}

with error:

token = ["println",<84>,line=1,col=1]
token = ["4",<194>,line=1,col=9]
Exception in thread "main" line 1:18: unexpected char: 0xFFFF
        at org.codehaus.groovy.antlr.parser.GroovyLexer.nextToken(GroovyLexer.java:687)
        at Main.main(Main.java:14)
Java Result: 1

If I replace '/' character with '*' or something else it works fine.
