title: Bad request from WebLogic on authenticate method Openstack4j
body: <p>I have a problem with sending authenticate request with openstack4j library on Weblogic. My weblogic.xml looks like this:</p>
  <pre><code>...
      &lt;wls:prefer-application-packages&gt;
        &lt;wls:package-name&gt;org.slf4j.*&lt;/wls:package-name&gt;
        &lt;wls:package-name&gt;com.fasterxml.*&lt;/wls:package-name&gt;
      &lt;/wls:prefer-application-packages&gt;
  ...
  </code></pre>
  <p>and I'm getting 400 bad request using authenticate:</p>
  <pre><code>
   private OSClient.OSClientV3 authenticate() {
          try {
              OSClient.OSClientV3 os = OSFactory.builderV3()
                      .endpoint(osProperties.getAuthUrl())
                      .credentials(osProperties.getUsername(), osProperties.getPassword(),
                              Identifier.byName(osProperties.getDomainName()))
                      .scopeToProject(Identifier.byId(osProperties.getProjectId()))
                      .authenticate();
              os.useRegion(osProperties.getRegion());
              return os;
          } catch (ResponseException exception) {
              log.debug(&quot;Error with authentication OS: {}&quot;, exception.getCause().getLocalizedMessage());
              throw exception;
          }
  
  
      }
  </code></pre>
  <p>Locally everthing works fine, also when I delete from weblogic.xml fasterxml to use weblogic one - it works fine then. However, I need to use fasterxml from pom (weblogic one cause errors in other part of app).</p>
  <p>Can someone help? ;)</p>
