I cannot find anything about that, maybe some of you smart people will have an insight :thinking_face: I'm consuming a Java lib in a Clojure program that does some networking using NIO ; compiling successfully to a native image. When running, more precisely when java.nio.channels.Selector is .wakeup , it crashes:

#error {
 :cause Bad file descriptor
 :via
 [{:type java.lang.InternalError
   :message java.io.IOException: Bad file descriptor
   :at [sun.nio.ch.KQueueSelectorImpl wakeup KQueueSelectorImpl.java 295]}

@adam678 I recommend posting this in the graalvm community slack as this might be a graalvm bug. Or open an issue about it directly
