Hello guys, As far as this issue is concerned (for what i have understood) i believe that one way to separate NULL(s) that occur from the A.P.I. from NULL(s) coming from wrong usage of A.P.I. by a user is the assert technique... I didn't know a lot about it but from what i have read it should be implemented only in the private methods of the A.P.I. Check this link out: " http://download.oracle.com/javase/1.4.2/docs/guide/lang/assert.html";. Another choice is to create a new class that would check all the arguments of every function we are interested in (for example: public checkArguments(Object... args)) [If i have understood correctly the purpose of this issue...]. Any suggestions would be more than welcomed!
Best regards, Giannakopoulos Michael
