The following test case, derived from Eclipse/ecj, fails to compile on HEAD and
current 4.0 branch. This is a regression since 4.0.0.

package ast;

import classfmt.*;
public abstract class ASTNode implements ClassFileConstants {
}

---

package ast;

public class EqualExpression extends ASTNode {
        public void resolveType() {
                long foo = JDK1_5;
        }
}

---

package classfmt;

public interface ClassFileConstants {
        int MINOR_VERSION_0 = 0;
        long JDK1_5 = (long) ClassFileConstants.MINOR_VERSION_0;
}


$ gcj -c ast/EqualExpression.java
./classfmt/ClassFileConstants.java: In class 'ast.EqualExpression':
