Eclipse compiler reports error "The constructor [...] is undefined", where there
is the constructor's name in the place of [...]. Program compiles perfectly with
Sun's JDK 1.5. What is more, the error is not reported after cleaning and
building whole project. Program also starts after clean & build. The
constructors TypedInput<T>( Class<T>) and TypedOutput<T>( Class<T>) are defined
in internal class as shown below. Eclipse's internal compiler reports 2 errors
in the method void test() complaing that constructor is undefined.

public class Processor 
{
	public static class Contract extends InputClass
	{
		int getInputIndex() { return 0; }
		
		boolean isRequired() { return true; }
		
		public int getNumber() {	return getInt( 0); }
		public Date getDate() { return getDate( 1); }
		public double getValue() { return getDouble( 2); }
	}

	public static class State extends OutputClass
	{
		int getOutputIndex() { return 0; }
		
		public void setNumber( int nr) { setInt( 0, nr);}
		public void setDate( Date data) { setDate( 1, data);}
		public void setValue( double stan) { setDouble( 2, stan);} 
		public void setDelay( int opoznienie) { setInt( 3, opoznienie);}
	}
	
	
	public class TypedInput< T extends InputClass>
