      Description

      I have this base Component (Page Fragment) Class:

      public abstract class Component {
       
      	protected WebElement getRoot() {
      		// ...
      	}
       
      	@Override
      	public boolean equals(Object obj) {
      		if (!(obj instanceof Component))
      			return false;
       
                      // WebElementUtils.equal is a ARQGRA-484 workaround, irrelevant here
      		return WebElementUtils.equal(getRoot(), ((Component) obj).getRoot());
      	}
       
      }
      

      The equals call results in an exception

      java.lang.RuntimeException: unexpected invocation exception during invocation of ru.argustelecom.system.inf.testframework.it.ui.comp.Component#getRoot(), on target 'ru.argustelecom.system.inf.testframework.it.ui.comp.AutoComplete@83ddf46d': Class org.jboss.arquillian.graphene.proxy.GrapheneProxyHandler can not access a member of class ru.argustelecom.system.inf.testframework.it.ui.comp.Component with modifiers "protected"

      Looking at the GrapheneProxyHandler code:

          protected Object invokeReal(Object target, Method method, Object[] args) throws Throwable {
              Object result;
              try {
                  if (target instanceof GrapheneProxyInstance) {
                      target = ((GrapheneProxyInstance) target).unwrap();
                  }
                  if (!method.getDeclaringClass().isInstance(target)) {
                      Method realMethod = target.getClass().getDeclaredMethod(method.getName(), method.getParameterTypes());
                      if (!realMethod.isAccessible()) {
                          realMethod.setAccessible(true);
                      }
                      result = realMethod.invoke(target, args);
                  } else {
                      result = method.invoke(target, args);
                  }
                  // ...
      

      This !method.getDeclaringClass().isInstance(target) check doesn't pass, so the accessibility modification is skipped. And naturally GrapheneProxyHandler doesn't have an access to Component#getRoot since it's in a different package and not a subclass.
