Hi Jason, Sorry to bug you here again. If you know where I can find the JLine issue tracker, could you let me know? Thanks. Until then ;) I believe I've found a bug in JLine's handling of unsupported terminals. Currently, when reading the input stream, when EOF is encountered, JLine will return empty string "". I believe it should return null in order to maintain consistency with supported terminal handling: *The current implementation:* /** * Read a line for unsupported terminals. */ private String readLine(final InputStream in) throws IOException { StringBuilder buff = new StringBuilder(); while (true) { int i = in.read(); if (i == -1 || i == '\n' || i == '\r') { return buff.toString(); } buff.append((char) i); } // return new BufferedReader (new InputStreamReader (in)).readLine (); } *Should probably be updated to:* /** * Read a line for unsupported terminals. */ private String readLine(final InputStream in) throws IOException { StringBuilder buff = new StringBuilder(); while (true) { int i = in.read(); if (i == -1) { return null; } else if (i == '\n' || i == '\r') { return buff.toString(); } buff.append((char) i); } // return new BufferedReader (new InputStreamReader (in)).readLine (); } Also, if performance is a reason for using the StringBuilder here, why not use a *static final EMPTY_STRING = "";* and return that? *The downstream issue, for reference:* https://issues.jboss.org/browse/SEAMFORGE-77 Thanks for your time. -- Lincoln Baxter, III http://ocpsoft.com http://scrumshark.com "Keep it Simple"
