If you browse to JLS 7.3: Compilation Units, you will see that a compilation unit (i.e., a Java source file) is composed of three high level elements, called PackageDeclaration, ImportDeclarations, and TypeDeclarations. All of them are optional, which clearly means that an empty compulation unit is a valid java file.
I hope this clears your doubts.
