No, the "charSet" is correct name. The issue is that instead of using "UTF-8" he used "UTF8", which caused null to be added to DPB and thus the error. But as I said, the driver should not cause such errors - property should be either completely ignored or should throw the exception before.

props.put("user", "sysdba");

c = java.sql.DriverManager.getConnection(databaseURL, props);

According to "http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html", used at August 21th, 2007, UTF8 seems to be a valid java name for an unicode encoding.
UTF8 is a "Cannonical Name for the http://java.io and java.lang API", UTF-8 is the "Canonical Name for java.nio API".
The following class, that is a variant of the given example,
produces the reported error on my computer:
package de.intermoves.eubicon;
import java.util.Properties;
public class TestCharSet {
public static void main(String args[]) throws Exception {
String databaseURL = "jdbc:firebirdsql://localhost/E:\\data\\projekte\\eubicon\\CSIntermoves\\application\\supplier\\222.333_139041777\\data\\Data.fdb";
} finally {
System.out.println("Closing database resources and rolling back any changes we made to the database.");
}
}
// Display an SQLException which has occured in this application.
private static void showSQLException(java.sql.SQLException e) {
// Notice that a SQLException is actually a chain of SQLExceptions,
