Description tln 2014-09-10 13:39:08 UTC 
public class BugDemo
{
	public static void setNumber(Integer value) {}
	public static void setNumber(Long value) {}
	
	public static void bug()
	{
		setNumber((Integer)null);   // (*)
	}
}

In this class NetBeans marks the line (*) with a warning bulb saying "Boxing of already boxed value". The recommended remedy is "Remove extra boxing". However, if I follow this advice, the code won't compile anymore. The compiler will complain "reference to setNumber is ambiguous" at this line.
