javac from 1.4.2 b18 cannot compile sources for Sun ONE Studio 5.0 "Nevada" = NetBeans 3.5, even after working around bug #4832887:

all-jarpackager:
Building module jarpackager...

init:

compile:
Compiling 72 source files to /space/src/nevada/nb_all/jarpackager/src
/space/src/nevada/nb_all/jarpackager/src/org/netbeans/modules/jarpackager/JarCompiler.java:104: abstract method equals(java.lang.Object) cannot be accessed directly
            return super.equals(obj) && (jc == other.jc);
                        ^
Note: Some input files use or override a deprecated API.
Note: Recompile with -deprecation for details.

The bug can be narrowed down to a small test case:

testabstractequals$ cat TestAbstractEquals.java
public class TestAbstractEquals {
    public interface I {
        boolean equals(Object o);
    }
    public abstract class A implements I {}
    public class B extends A {
        public boolean equals(Object o) {
            return super.equals(o);
        }
    }
}
testabstractequals$ /space/jdk1.4.2-beta-b18/bin/javac TestAbstractEquals.java
TestAbstractEquals.java:8: abstract method equals(java.lang.Object) cannot be accessed directly
            return super.equals(o);
                        ^
1 error
testabstractequals$ /space/jdk1.4.1_01/bin/javac TestAbstractEquals.java
testabstractequals$

Of course super from B.equals refers to Object.equals which is not abstract.

This is a regression from 1.4.1_01.
