Description

For various reasons we are still using the now deprecated DefaultHttpClient. After updating to 4.3 we encountered a NullPointerException in a seldom case involving proxies and AuthCache.

    @Test
    public void testDefaultHttpClientProxyAndAuthCache() throws Exception {
        try (CloseableHttpClient client = new DefaultHttpClient()) {
            ConnRouteParams.setDefaultProxy(client.getParams(), URIUtils.extractHost(URI.create("http://example.org")));
            HttpClientContext context = HttpClientContext.create();
            context.setAuthCache(new BasicAuthCache());
//          java.lang.NullPointerException (null route)
//          at org.apache.http.client.protocol.RequestAuthCache.process(RequestAuthCache.java:88)
//          at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:131)
            HttpResponse resp = client.execute(new HttpGet("https://www.example.org"), context);
            EntityUtils.consumeQuietly(resp.getEntity());
        }
    }

Thanks in Advance.
