I've found a discussion regarding the "null parameter waring" problem on sun's forum.
http://forum.java.sun.com/thread.jspa?threadID=592301&tstart=75 This is the warning: >[javac] cast to java.lang.Object for a varargs call >[javac] cast to java.lang.Object[] for a on-varargs call and to suppress this >warning The problem is that some of the reflection methods called (getConstructor(), invoke(), newInstance(),...) changed in 1.5 to take varargs and the cast of null is need as reported in the warning (to Object[]).
