potential problem: CometEvent END is not fired

[stzdzyhs]

Hello,
a basic CometProcessor servlet, I found that the CometEvent END is not 
fired.only BEGIN event is fired.
(tested on 7.0.34 and the latest 7.0.42)
please use a browser to access the servlet

BWT, it seems that the org.apache.tomcat.dbcp.dbcp.BasicDataSource code 
missing in the svn:tc7.0.x/trunk,
can you please have a check ?

Thanks!

        System.out.println("Event: " + event + " req:" + request  + "

String(buf, 0, n) );
                }
                else if (n < 0) {
                    System.out.println("Read <0, EOS ?");
                    return;
