ABSTRACT
While a typical software component has a clearly specified
(static) interface in terms of the methods and the input/out-
put types they support, information about the correct se-
quencing of method calls the client must invoke is usually
undocumented. In this paper, we propose a novel solution
for automatically extracting such temporal specifications for
Java classes. Given a Java class, and a safety property such
as "the exception E should not be raised", the correspond-
ing (dynamic) interface is the most general way of invoking
the methods in the class so that the safety property is not
violated. Our synthesis method first constructs a symbolic
representation of the finite state-transition system obtained
