ArrayIndexOutOfBoundsException in Encoding.decodeUTF8()

java.lang.ArrayIndexOutOfBoundsException: 3
         at org.postgresql.core.Encoding.decodeUTF8(Encoding.java:253)
         at org.postgresql.core.Encoding.decode(Encoding.java:165)
         at org.postgresql.core.Encoding.decode(Encoding.java:181)
         at
org.postgresql.jdbc1.AbstractJdbc1ResultSet.getString(AbstractJdbc1ResultSet.java:97)

The relavent code is:

        while (i < k) {
            z = data[i] & 0xFF;
            if (z < 0x80) {
                l_cdata[j++] = (char)data[i];
                i++;
            } else if (z >= 0xE0) {        // length == 3
                y = data[i+1] & 0xFF; //<<== THIS IS LINE 253
                x = data[i+2] & 0xFF;
                val = (z-0xE0)*pow2_12 + (y-0x80)*pow2_6 + (x-0x80);
                l_cdata[j++] = (char) val;
                i+= 3;
            } else {        // length == 2 (maybe add checking for length > 3, throw exception if it is


And in the method that calls that:

    if (encoding.equals("UTF-8")) {
                    return decodeUTF8(encodedString, offset, length);
                }

The thing is my database encoding is SQL_ASCII

=> SELECT version(),  getdatabaseencoding() ;
                                                  version
                 | getdatabaseencoding

---------------------------------------------------------------------------------------------------------+---------------------
  PostgreSQL 7.3.1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2 20020903 (Red Hat
Linux 8.0 3.2-7) | SQL_ASCII
(1 row)

... so why is it trying to decode the string as UTF-8?  I just upgraded this database from
7.2.3 yesterday.
