Bug in java.dyn.MethodHandles.unreflect

one):

Exception in thread "main" java.lang.NullPointerException
    at java.dyn.MethodHandles.unreflect(MethodHandles.java:294)

    at fr.umlv.indy.visitor.test.Main$1.<init>(Main.java:7)
    at fr.umlv.indy.visitor.test.Main.main(Main.java:7)

if (constraint != defc && !constraint.isAssignableFrom(defc)) {
                                     oups ----------^
