CLASS
Annotations are to be recorded in the class file by the compiler
but need not be retained by the VM at run time. This is the default
behavior.
public
static
final
RetentionPolicy
RUNTIME
Annotations are to be recorded in the class file by the compiler and
retained by the VM at run time, so they may be read reflectively.
