Unite test failing - for com.day.commons.httpclient

Hi All,

We have upgraded our AEM version from 6.2 to 6.5.6. While updating our codebase we observed that our unit test cases are failing for com.day.commons.httpclient class showing below error : 

java.lang.NoClassDefFoundError: com/day/commons/httpclient/impl/ProxyWrapper

at org.apache.commons.httpclient.HttpState.<init>(HttpState.java:114)
at org.apache.commons.httpclient.HttpClient.<init>(HttpClient.java:183)
at org.apache.commons.httpclient.HttpClient.<init>(HttpClient.java:97)

Unite test code looks like below : 

@Test
public void provideHttpClient_singleton() {

    Injector injector = Guice.createInjector(peaberryRssClientModule);

    HttpClient httpClientA = injector.getInstance(HttpClient.class);
    HttpClient httpClientB = injector.getInstance(HttpClient.class);

    assertEquals(httpClientA, httpClientB);

}

I assume that Uber 6.5 jar provide httpclient version of 4.5.2 and due to which it it giving error for HttpState(which is deprecated list of AEM 6.5). Any quick solution to fix this?
