Method getPackageName

guava/src/com/google/common/reflect/Reflection.java:35–37

Returns the package name of {@code clazz} according to the Java Language Specification (section 6.7). Unlike {@link Class#getPackage}, this method only parses the class name, without attempting to define the {@link Package} and hence load files.
