Major Description
When running unit tests in org.apache.oodt.cas.protocol.ftp.TestCogJGlobusFtpProtocol on a system that already has a service bound to TCP port 9000 on all interfaces, an error message appears:
testLSandCDandPWD(org.apache.oodt.cas.protocol.ftp.TestCogJGlobusFtpProtocol): Failed to bind to address 0.0.0.0/0.0.0.0:9000, check configuration
The stack trace is:

The offending code has a hard-coded port number:
TestCogJGlobusFtpProtocol.java
public class TestCogJGlobusFtpProtocol extends TestCase { private static final int PORT = 9000; private FtpServer server; ...
On computers where a service is already bound to this port, the test case fails to set up its FTP server necessary for the test to run.
Using a system-assigned port, or trying incrementing port numbers up to a limit, would be better ways to avoid this issue.
