Re: Does --add-exports imply --add-reads??

There seems to be a javac bug here, I've created the following to track it:

Hi,

Given these sources:

src/mod.one/module-info.java
//---
module mod.one {
        requires transitive java.sql;
}
//---

src/mod.one/p/X.java
//---
package p;
public class X {
        public static java.sql.Connection getConnection() {
                return null;
        }
}
//---

src/mod.two/module-info.java
//---
module mod.two {
        requires java.sql;
}
//---

src/mod.two/q/Y.java
//---
package q;
public class Y {
   java.sql.Connection con = p.X.getConnection();
}
//---

Javac accepts the program when invoked like this:

$ javac -d bin -source 9 --module-source-path src --add-exports mod.one/p=mod.two \

   src/mod.one/module-info.java src/mod.one/p/X.java \
   src/mod.two/module-info.java src/mod.two/q/Y.java

How come javac allows Y.java to access p.X, although mod.two does not read mod.one?

Is javac interpreting --add-exports to imply an additional --add-reads?

best,
