[kaffe] hsqldb - Abstract method in non-abstract class error

I'd like to use hsqldb 1.7.1 for the simple regression testing reporting
thing I'm writing to install on kaffe.org, but I'm running into a bug.

It's super cool, BTW.  Get it here:


Here's a trivial example, that creates a SQL table in-memory.

import java.sql.*;
public class TestHSQLDB {
    public static void main(String[] args)
        throws ClassNotFoundException, SQLException {
        Connection con = DriverManager.getConnection(
            "jdbc:hsqldb:.", "sa", "");
        Statement stmt = con.createStatement();
        stmt.executeUpdate("create table TestResults " +
                "(codebase varchar(50), " +
                " branch varchar(50), " +
                " change integer, " +
                " category varchar(128), " +
                " status varchar(20) )");

$ kaffe -cp .:../webapp/WEB-INF/lib/hsqldb.jar TestHSQLDB
java.lang.ClassFormatError: (class: org/hsqldb/jdbcConnection, method: setHoldability signature: (I)V) Abstract method in non-abstract class
   at java.sql.DriverManager.getConnection (DriverManager.java:164)
   at java.sql.DriverManager.getConnection (DriverManager.java:188)
   at TestHSQLDB.main (TestHSQLDB.java:10)

This blocks me, so I'll definitely dive into it this weekend - but I
thought somebody on the list might be able to fix it faster.
