I've created an isEqualThree function
public static boolean isEqualThree(Annotation a, Annotation b, Annotation c){
if(isEqual(a,b) || isEqual(b,c) || isEqual(a,c)){
return true;
}
return false;
}
By the way, it works also with overloading, I've never had problems with
overloading in Drools. And I've tested also with different names, the problem
remains, even using different function names.

Your condition works without problems using the isEqualThree function, it works
also if I overload the function. It also works if I put the isEqual condition out
of the eval, into the object constraints. But if I want to use my primary idea, using
different names,
public static boolean isEqualMore(Annotation... a)
I still get the same error from the isEqualMore function.

Yes, Java, but.

Suspicious, may have to raise a JIRA.
Experiment 1
Please write isEqualThree for 3 Annotation arguments and use this,
just to make sure that these Problems are caused by Drools. (Do NOT
rely on overloading, use another name.)
Experiment 2
Using the isEqual as it is now, rewrite the last pattern as:
not ( $a5:ODMAnswer(
isInAnnotation($a1,$a5),
isBigger($a3,$a5) )
and
eval( ! isEqual($a3,$a4,$a5) )
)
