We note that BugID: 4674826 is fixed in 142 release.

However, java.net.Socket checks for old-style impls like this:

    private void checkOldImpl() {
    if (impl == null)
        return;
    // SocketImpl.connect() is a protected method, therefore we need to use
    // getDeclaredMethod, therefore we need permission to access the member
    try {
        AccessController.doPrivileged(new PrivilegedExceptionAction() {
            public Object run() throws NoSuchMethodException {
            Class[] cl = new Class[2];
            cl[0] = SocketAddress.class;
            cl[1] = Integer.TYPE;
            impl.getClass().getDeclaredMethod("connect", cl);
            return null;
            }
        });
    } catch (java.security.PrivilegedActionException e) {
        oldImpl = true;
    }
    }

However, my understanding is that this will exclude inherited methods on the impl. In our instance we have a BSocketImpl that inherits from ASocketImpl where only ASocketImpl has the appropriate connect() method. java.net.Socket therefor wrongly assumes that it is an old-style impl.
