The methods equals(DataFlavor df), equals(String mt), equals(Object
mt) of class java.awt.datatransfer.DataFlavor throw
NullPointerException if class instance was created with constructor
DataFlavor().

The doc says:
--------------------------------------------------
public boolean equals(DataFlavor dataFlavor)
      Returns:
            if the DataFlavors represent the same type.

public boolean equals(java.lang.Object o)
      Returns:
            if the objects are equal
      Overrides:
            equals in class java.lang.Object

public boolean equals(java.lang.String s)
      Returns:
            if the String (MimeType) is equal

Here is the test demonstrating the bug:
-----------------Test.java------------------------
import java.awt.datatransfer.*;

public class Test {
      public static void main(String[] args) {
DataFlavor df = new DataFlavor();
try {
System.out.println(df.equals((Object)new DataFlavor()));
} catch (Exception e) {
System.out.println("equals(Object): "+e);
}

try {
System.out.println(df.equals(new DataFlavor()));
} catch (Exception e) {
System.out.println("equals(DataFlavor): "+e);
}

try {
System.out.println(df.equals("application/postscript;class=java.awt.datatransfer.DataFlavor"));
} catch (Exception e) {
System.out.println("equals(String) "+e);
}
    }
}
---------Output from the test---------------------
equals(Object): java.lang.NullPointerException
equals(DataFlavor): java.lang.NullPointerException
equals(String): java.lang.NullPointerException
