Static invocation? There's no "static invocation" in
the code you provided.

There's no interface here; what interface are you
talking about?
Someone already pointed out that unless you call a
super ctor that sets or explicitly set the
RequestHandler member variable it obviously won't be
valid.
The sample you provide does not declare an access
modifier for reqHandler; IIRC the default is
'package-private' which means that a subclass in the
same package would have access to the member variable.
