But one thought is to prepend a special character (say "+") to the property name and add a sentence to the `java.security` file that the `+include` property is not exposed in the `Security` API. It could also be added as an implementation note to the `Security` API. Since this property is JDK specific, I think an implementation note would be acceptable.

@seanjmullan @wangweij , is there anything else that you would like to discuss regarding this proposal?
