^G^XThe java.lang.reflect.Field.set(Object, Object) method throws an
IllegalArgumentException if the first Object argument is not an instance of the
class or interface declaring the field, or if the second Object argument is
incompatible with the field type. Currently the IllegalArgumentException
message string is left blank. Including information about the expected and
incompatible argument types in the exception message string would make stack
traces resulting from such failures more informative.
