Can we be specific about the fix is made in SdkHttpFullRequest

Fixed an issue in SdkHttpFullRequest where constructing with a query string consisting of a single \"=\" would throw an ArrayIndexOutOfBoundsException.

or something that is more specific ?

Also for completeness can we add test in SdkHttpRequestResponseTest since this tests the Public API

    @Test
    public void testSdkHttpRequestWithEmptyEqualQueryParameterName() {
        final String expected = "http://example.com?=";
        URI myUri = URI.create(expected);
        SdkHttpRequest actual = SdkHttpRequest.builder().method(SdkHttpMethod.POST).uri(myUri).build();
        assertThat(actual.getUri()).hasToString(expected);
    }

This test will fail because our current implementation will eliminate "=" when there are no query values. I added a test that the expected result string is "http://example.com?"

public void uriParamsWithSingleEqualQuery() throws URISyntaxException {
URI uri = URI.create("http://example.com?=");
Map<String, List<String>> uriParams = SdkHttpUtils.uriParams(uri);
assertThat(uriParams).isEmpty();

Consider

    @Test
    public void uriParamsWithEmptyKeyAndValue() throws URISyntaxException {     //Interested
        URI uri = URI.create("http://example.com?=myValue");
        Map<String, List<String>> uriParams = SdkHttpUtils.uriParams(uri);
        System.out.println("uriParams " +uriParams);

    }

For http://example.com?=myValue the uriParams looks like
uriParams {=[myValue]}

If you see here the Key in the Map is empty .

Now based on this for "http://example.com?=" we should have empty key with empty list or null as below
uriParams {=[]}or uriParams {=null} ?

Discussed offline, {=null} conforms with current implementation
