Currently, the system supports:

    enum Param{ONE,TWO,THREE}

    @GET
    Public Response method(@QueryParam(“param”) List<Param> params)

But not:

    enum Param{ONE,TWO,THREE}

    @GET
    Public Response method(@QueryParam(“param”) EnumSet<Param> params)

EnumSet has better methods for manipulating enums.
