Connecting the driver to MySQL 4.10 depending of the type of the columns DataBaseMetaData.getColumns throws an ArrayIndexOutOfBoundsException. The nightly snapshot shows the same behaviour.

How to repeat:
Connect the driver to a MySQL 4.10 server.
Execute DataBaseMetaData.getColumns on a table containing a column of type TEXT.

Suggested fix:

                    if (typeInfo != null) {
                        if ((typeInfo.indexOf("enum") != -1)
                                || (typeInfo.indexOf("set") != -1)) {
                            String temp = typeInfo.substring(typeInfo.indexOf(
                                        "("), typeInfo.lastIndexOf(")"));


                        int delimPos = typeInfo.indexOf('(');
                        int setPos = typeInfo.indexOf("set");
                        if (delimPos > 0 && ((typeInfo.indexOf("enum") != -1)
                                             || (setPos != -1 && setPos < delimPos))) {
                            String temp = typeInfo.substring(delimPos, typeInfo.lastIndexOf(")"));

works for me.
typeInfo comes in as "text character set latin1" and "set" is interpreted as the columns type in the unfixed snipplet. OTOH the character set may be not expected here.

Thank you for your bug report. This issue has already been fixed

This should already be fixed in the nightly builds of Connector/J 3.0.8 and 3.1.0 (see http://mmmysql.sourceforge.net/snapshots).

Sorry, I closed this as already fixed, but it is a different bug. This will be patched ASAP!

Thank you for your bug report.

Fixed in the source trees. You should be able to test it with a nightly snapshot of either 3.0 or 3.1 from http://mmmysql.sourceforge.net/snapshots/

Thanks for your bug report!
