Specification j.l.constant.DirectMethodHandleDesc.Kind.valueOf(int)
( https://download.java.net/java/early_access/jdk17/docs/api/java.base/java/lang/constant/DirectMethodHandleDesc.Kind.html#valueOf(int) )
says:

> Returns the enumeration member with the given refKind field. Behaves as if valueOf(refKind, false). As a special case, if refKind is REF_invokeInterface (9) then the isInterface field will be true.

However if we call

    Kind.valueOf(MethodHandleInfo.REF_invokeInterface);

then IAE is thrown

   java.lang.IllegalArgumentException: refKind=9
at java.base/java.lang.constant.DirectMethodHandleDesc$Kind.valueOf(DirectMethodHandleDesc.java:149)
at java.base/java.lang.constant.DirectMethodHandleDesc$Kind.valueOf(DirectMethodHandleDesc.java:111)

As if we call

    Kind.valueOf(MethodHandleInfo.REF_invokeInterface, false)

and not as if the last arg is 'true'.
