DebugException in apache-commons-net

Question

When i try to list files from my location using ftpClient.listFiles("folder"); it shows

org.eclipse.debug.core.DebugException: com.sun.jdi.ClassNotLoadedException: Type has not been loaded occurred while retrieving component type of array.

Can some one guide me what i am doing wrong.

I use apache-commons-net-3.3

My code is

FTPClientConfig ftpClientConfig = new FTPClientConfig(FTPClientConfig.SYST_NT);
FTPClient ftpClient = new FTPClient();
ftpClient.configure(ftpClientConfig);
ftpClient.connect(hostName, Integer.valueOf(portNumber));
ftpClient.enterLocalPassiveMode();
ftpClient.login(username, password);

// Error throws here
FTPFile[] files = ftpClient.listFiles("folder");

This Exception is thrown when a user gave a Wrong or Encrypted Username Or Password.

Apache is not throwing the correct exception.
