sample source code to reproduce the bug

The Eclipse built-in Java compiler fails to report an error if the type is private. This is inconsistent with the Sun javac 1.6.0_06 compiler.

See the attached source code for an example. Try it in Eclipse, and then from the command line. Eclipse reports no errors, but javac reports this error.

Superclass.java:5: Subclass.NestedSubclass has private access in Subclass
class Subclass extends Superclass<Subclass.NestedSubclass> {
                                          ^
1 error

Reproduced in latest, with corrected testcase:

public class X<T> {
}
class Subclass extends X<Subclass.NestedSubclass> {
	@SuppressWarnings("unchecked")
	private final class NestedSubclass extends X {
	}
} 

Both java6 and 7 do complain.
Comment 2 Philipe Mulet CLA 2008-06-18 12:59:38 EDT 
Feels strange than an access to a private type be forbidden within enclosing type...

like this code doesn't raise any error:
public class X<T> {
}
class Subclass extends X<Object> {
	Subclass.NestedSubclass nested;
	@SuppressWarnings("unchecked")
	private final class NestedSubclass extends X {
	}
} 

Feels like a javac bug to me.

See also bug 185422.

Indeed, this is a dup.
