"Failed to find constructor f java.nio.DirectByteBuffer: $s", #136

Closed DegenApeDev closed 3 years ago

DegenApeDev commented 3 years ago

I'm trying to run the example and I am getting this.. I'm not sure what I am doing wrong.

When I run 'lein run' from terminal:

I bet that has to do with your java version. They removed nio buffer constructors in JDK-14. What JDK version are you running?

This is fixable because jna also contains pointer->bytebuffer pathways that are compiled in via JNI.

DegenApeDev commented 3 years ago

Yep I am running 14.. What version would you recommend to run for this?

cnuernber commented 3 years ago

I have given guarantees to always work on Java 8 to quite a few people.

Ok thank you!
