Enum.values() not working in GWT throws compilation error

I'm using an enum class in my GWT class.I'm using enum.values() in order to iterate through the enum class. this throws error during complilation. the GXT version i'm using is 2.2.5. gwt-dev jar version is 2.4.0

Tried using EnumSet.allOf(DaysOfWeekEnum.class) still getting same error

This article -> https://github.com/gwtproject/gwt/issues/7065 says that it was a bug with gxt. but could not find a fix from it

    for (DaysOfWeekEnum day : DaysOfWeekEnum.values()) { 
        System.out.println(day); 
    }

Getting the below exception:

Got it fixed by adding the Enum class package under source path="" in gwt.xml.

<source path='myapplication/enums/'/>
