Using the -verbose or -v flag with javap version 1.7 or later will show the retained annotations.

Example:

javap -p -v ./services/target/windup-web-services/WEB-INF/classes/org/jboss/windup/web/services/model/RegisteredApplication.class

 #50 = Utf8   Ljavax/persistence/Column;
 #64 = Utf8   Lorg/jboss/windup/web/services/validators/NotBlankConstraint;
 #67 = Utf8   Ljavax/validation/constraints/Size;

private java.lang.String title;
  descriptor: Ljava/lang/String;
  flags: ACC_PRIVATE
  RuntimeVisibleAnnotations:
    0: #50(#62=I#63)
    1: #64(#65=s#66)
    2: #67(#68=I#69,#70=I#63,#65=s#71
