EBean inside inner class

``` java
@EBean
public class MyClass {

// ... some methods of my class ...

@EBean
static class StringResourcesOfMyClass {

@StringRes
static String myString;

@StringRes
static String myStringAnother;

}
```

Gives me an error like:
The package com.test.MyClass collides with a type   

StringResourcesOfMyClass_.java  /MyProject/.apt_generated/com/test/MyClass line 6   Java Problem
