Compile and get javap's output for any class that contains final fields with "-constants" option, e.g.
class SimpleClass {
public final String FINAL_CONSTANT = "Lorem ipsum dolor sit amet...";
public static String STATIC_CONSTANT = "Lorem ipsum dolor sit amet...";
public static final String STATIC_FINAL_CONSTANT = "Lorem ipsum dolor sit amet...";
}
The output message contains the value of the non-static final field:
....
public final java.lang.String FINAL_CONSTANT = "Lorem ipsum dolor sit amet...";
public static java.lang.String STATIC_CONSTANT;
public static final java.lang.String STATIC_FINAL_CONSTANT = "Lorem ipsum dolor sit amet...";
....
According to the help message only the "static final" constant values should be included ("-constants Show static final constants")
