>Description:
I don't think the following code is legal. The
ProtectedInnerInterface class is in the global
package and it has a protected member Inter
that should not be accessible.


% cat ProtectedInnerInterface.java
// File ProtectedInnerInterface.java

public class ProtectedInnerInterface {
    protected interface Inter {}
}


% cat ProtectedInnerInterface_OtherPkgTest3.java
// File ProtectedInnerInterface_OtherPkgTest3.java

package foo;

import ProtectedInnerInterface;

public class ProtectedInnerInterface_OtherPkgTest3 implements ProtectedInnerInterface.Inter {}

// This should fail to compile because the Inter member of ProtectedInnerInterface
// is protected and therefore should not be accessible.




% javac ProtectedInnerInterface.java ProtectedInnerInterface_OtherPkgTest3.java
ProtectedInnerInterface_OtherPkgTest3.java:11: Can't access nested interface ProtectedInnerInterface. Inter. Only public classes and interfaces in other packages can be accessed.
public class ProtectedInnerInterface_OtherPkgTest3 implements ProtectedInnerInterface.Inter {}
                                                              ^
1 error


% jikes -classpath /usr/share/kaffe/Klasses.jar ProtectedInnerInterface.java ProtectedInnerInterface_OtherPkgTest3.java

(No error generated)


% gcj -C ProtectedInnerInterface.java ProtectedInnerInterface_OtherPkgTest3.java

(No error generated)


So it seems like both jikes and gcj are wrong to compile this code. Only javac
seems to get it right.

 I agree, the same problem applies to a "protected static" inner class, which javac (1.3) fails but gcj and jikes accept.
 
 However, cases like this, where gcj compiles technically illegal code, should perhaps be assigned a lower priority than bugs where gcj fails to compile legal code.
