Tests whether calls from Java into Lisp can work.
check-lisp-calls-initialized => result
t if Lisp calls have been initialized successfully, which means that calls from Java into Lisp can work.
The main factor that may affect successful initialization of Lisp calls is the availability of the class com.lispworks.LispCalls, which comes from LispWorks and will not be available if you do not make it available to the Java Virtual Machine in some way.
On Android the
LispCalls class is available because it is in the
lispworks.jar file that must be included in the application.
