cannot find symbol?

 Basically I am passing a String array to a method (verify) defined in a
 generic way in an interface in order to create an object of a certain type

 I am checking that the object of the correct type is created but when I try
to call a method java tells me "cannot find symbol"

 I squinted at it for a while, but can't see what is wrong with it

 What is wrong with this code? How do you fix that problem? Does it relate
to the use of generic declarations and/or reflection?

 thanks,
