    initialization: when resolving method
    "javax.swing.text.JTextComponent$1.dropLocationForPoint(
    Ljavax/swing/text/JTextComponent;Ljava/awt/Point;)Ljavax/
    swing/TransferHandler$DropLocation;" the class loader (instance of
    org/powermock/core/classloader/MockClassLoader) of the current
    class, javax/swing/text/JTextComponent$1, and the class loader
    (instance of <bootloader>) for interface
    sun/swing/SwingAccessor$JTextComponentAccessor have different Class
    objects for the type mponent$1.dropLocationForPoint(Ljavax/swing/text/
