com.Ostermiller.util.NoCloseInputStream
public class NoCloseInputStream
An input stream with a close method with no effect. More information about this class is available from ostermiller.org.
This class is designed to wrap a normal input stream so that it can be passed to methods that read from it and may erroneously close it. This class is a workaround when the method cannot be modified because it is in a library.
