Use eq in mockito

When using mockito, we should use eq for String. It seems that we should use eq even for long.

If we foget to use it as follows:

when(mockService.method(longValue, any(ClassA.class))).thenReturn(true);

You will get the following error.

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers!
2 matchers expected, 1 recorded:
-> at com.example.XxxTest.test(XxxTest.java:51)

This exception may occur if matchers are combined with raw values:
    //incorrect:
    someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
    //correct:
    someMethod(anyObject(), eq("String by matcher"));
