Function rules support for autoboxing/unboxing primitive java types
Since version 1.5 Java support autoboxing/unboxing.
https://docs.oracle.com/javase/tutorial/java/data/autoboxing.html
Currently if you create a function with an "Integer" parameter and try to pass it an "int" it won't save the rule as it considers it invalid. Runtime it'll work as Java handles the type mismatch. Is there any plan to address this?
