java version "1.2.2"
Classic VM (build JDK-1.2.2-U, native threads, symcjit)

start a url connection where the protocol is FTP.

As part of the sun.net.www.protocol solution, a thread
sun.net.www.protocol.ftp.FtpDirectoryThread, is created.

That thread cannot be stopped by any method. That includes, interrupt() and
interrupt(Throwable), and no methods are included in the implementation to abort
its execution either.
