ERROR BufferCleaner$ - ByteBuffer cleaner not initialised.

I tried to call scala methods from java 8.

Java version:

java version “1.8.0_171” Java™ SE Runtime Environment (build 1.8.0_171-b11) Java HotSpot™ 64-Bit Server VM (build 25.171-b11, mixed mode)

And found an error in program log:

It seems that latest library isn’t compartible with java 8.

[javadev]

I tested it locally. No errors in log. Good job!

I’ve pushed v0.8-beta.5 with a reflection based java8 cleaner. Please try it with the release.

We need configure travis to run tests for each build so we can test on multiple JVM versions as soon as possible to avoid these issues. I will keep updating on the progress of tests execution via travis in #4.
