Due to security concern, we are upgrading drools versions in our project from 7.44.0.Final to 7.64.0.Final

And since then we are facing some unresolvable issues.

1. One of the issue, I have logged the details in stackoverflow. Please refer the link below:

Passing http url in a rule throws exception in latest drools versions(v7.64 onwards) - Stack Overflow

So, I downgraded the Drools versions to 7.57.0.Final and the above error was not occurring but another one came.

1. Another issue which I encountered is that "java.lang.ArrayIndexOutOfboundexception" in MvelConstraint.java.

Please refer drl sample:

when

        $r1  : Fact(path == \"Resource1\" )

        $r2 :  Fact(path == \"Resource2\" , ((this.get(\"address.first()\") deepContains $r1.get(\"address.first()\"))))

then      

        —

 end

While analyzing further,  the flow does go to the public void loadHandles(InternalFactHandle[] handles, InternalFactHandle rightHandle) & private static InternalFactHandle getFactHandle(Declaration declaration, InternalFactHandle[] handles) in the EvaluatorWrapper.class file. But the variable "rightHandle" is pointed at the lefthand side object(i.e. r2 instead of r1). So that's why I am raising this concern.
