Falling test[s]:
        java/net/Authenticator/B4769350.java

RegTest-test java/net/Authenticator/B4769350.java test hangs on our Windows ME machine.
Such a behaviour is caused by the following circumstances:
Regression test base for Mantis b08 contains the new file EmbeddedURLCallback.java containing
the following bug in it:

    public void request (HttpTransaction msg) {
        URI uri = msg.getRequestURI();
        Request req = (Request) requests.get (uri);

...

        req.next();

        if (req.finished()) {
            requests.remove (req);
        }
    }

The requests map uses URIs as keys but remove is called for req.
As a result, the server generates warnings on subsequent requests and does not handle it appropriately.

Clients of java/net/Authenticator/B4769350.java sometimes produces more than two requests, but this is another issue.

After I had changed the code as follows:

requests.remove (uri);

The test stopped hanging and produced sensible information meaning that all clients (c1, c2, c3, c4) were authenticated and retrived 'Hello's but some of them
sent more than two requests:

java.lang.RuntimeException: Authenticator was called 6 times. Should be 2

JavaTest Message: Test threw exception: java.lang.RuntimeException: Authenticator was called 6 times. Should be 2




It also worth to apply the following fixes in sun/net/httptest/HttpServer.java:

private String readLine (InputStream is) throws IOException {
...

return new String (b, 0, l); // was "return new String (b)" which returned a large string padded with zeroes.
}
