If x is a class member, the change remains.
If x is a static class field, the change remains.
Each method in java receives a copy of the variable
(pointing to the same object of course) we are passing.
If you are talking about the implementation of consequences in DRL,
this may be so; but it isn't a necessity to be implemented in this
way. In particular, the Expert documentation doesn't raise any "red
flags" along these lines.
