Current implementation of Java Code Coverage Tool
does not shutdown used socket before the end of execution.
To reproduce the bug please try to execute the following
class with Jcov JVMPI agent '-server_port' option:
------------ Source Begin --------------------
public class Hello extends Thread {
    public static void main(String[] args) {

        try {
            sleep(2000);
        } catch(InterruptedException ie) {
        }
        System.out.println("Hello world!");
    }
}
------------ Source End ----------------------
------------ Script Begin --------------------
#!/usr/bin/ksh
uname -a
export JCOV_JAR=/net/linux-11/export/home/gary/QA.JCOV/ws/image/lib/jcov.jar
export CLASSPATH=${JCOV_JAR}:.
export TESTED_PORT=10004
export JDK=/net/linux-11/export/home/jdk1.4.1/solaris-sparc

$JDK/bin/java -showversion -Xrunjcov:sp=$TESTED_PORT Hello &
$JDK/bin/java -showversion com.sun.tdk.jcov.grabber.Main -once -port=${TESTED_PORT}
sleep 5
netstat -a|grep $TESTED_PORT
echo 'End of test'
