Hi all,
I have an inexplicable runtime error with a leiningen-generated AOT uberjar
that happens when using Clojure 1.10 that doesn't happen with 1.9 (I'm on
Java 8 for both compilation and deployment).
The code in question looks like:
(defn make-apns-message [payload]
(let [buffer (ByteBuffer/allocate 3072)]
(doto buffer
(.put (byte 2))
(.position (int 5)) ;; this fails
(.put (byte 1))
;;<more .put's etc>
(.flip))
(Unpooled/wrappedBuffer buffer)))
When compiled with Clojure 1.10, the call to .position triggers this at
runtime:
java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/
ByteBuffer;
at basis.apns$make_apns_message.invokeStatic(apns.clj:255)

It's very strange because there is only one variant of position
<https://docs.oracle.com/javase/8/docs/api/java/nio/Buffer.html#position-int->
in a ByteBuffer that takes a parameter (and I'm compiling with
*warn-on-reflection* set to catch this sort of thing).
Any ideas?
Cheers,
Matt.
