Somewhat related, I had this code which "worked" on Alpha 2:
(defn ^java.nio.ByteBuffer to-byte-array [^com.eaio.uuid.UUID u]
(let [lo (.getClockSeqAndNode u)
hi (.getTime u)]
(-> (java.nio.ByteBuffer/allocate 16)
(.putLong hi)
(.putLong lo)
(.array))))
(can anyone spot the error?)
…which gave this exception on Alpha 3:
[exec] Caused by: java.lang.ClassCastException: [B cannot be cast to
java.nio.ByteBuffer
[exec] at
worldsingles.data.uuid$to_byte_array.invokeStatic(uuid.clj:33)
[exec] at worldsingles.data.uuid$to_byte_array.invoke(uuid.clj)
[exec] at
worldsingles.data.uuid$uuid_as_byte_array.invokeStatic(uuid.clj:36)
[exec] at worldsingles.data.uuid$uuid_as_byte_array.invoke(uuid.clj)
[exec] at
worldsingles.news$add_basic_event_data.invokeStatic(news.clj:24)
[exec] at worldsingles.news$add_basic_event_data.invoke(news.clj)
Changing it to the following solved the problem:
(defn ^bytes to-byte-array [^com.eaio.uuid.UUID u]
(let [lo (.getClockSeqAndNode u)
hi (.getTime u)]
(-> (java.nio.ByteBuffer/allocate 16)
(.putLong hi)
(.putLong lo)
(.array))))
It returns a byte[] not a java.nio.ByteBuffer. I actually had three functions
with this incorrect type hint (that, yes, all failed on Alpha 3).
I’m assuming that direct linking is causing return type hints to be a) static
class names — which is breaking Rangel’s code — and b) are more strictly
type-checked — which is breaking my code?
(we’re continuing to run tests on Alpha 3 but this is what we tripped over
immediately)
