Exception in thread "main" java.lang.NullPointerException

Solved. Just needed to install audio drivers.

Hi, recently switched my server where I do this from Ubuntu to Arch. Previously worked fine, now getting this error.

Using java-14-openjdk, but also tried 11, 8 & 7. Overlooked dependencies or should be using a different Java package, or what might be going on? Finds the input dir/files fine. Error comes as soon as it begins processing.

Exception in thread "main" java.lang.
at autostepper.AutoStepper.analyzeUsingAudioRecordingStream(AutoStepper.java:
at autostepper.AutoStepper.main(AutoStepper.java:100)

Update: Works on my local Arch machine, same Java 14. So the server must be missing something. Any thoughts?

Had the same problem on WSL with Ubuntu 20 with openjdk version "11.0.13" 2021-10-19. I ended on Windows on Java openjdk version "1.8.0-292"

WIndows:

> java -version
openjdk version "1.8.0-292"
OpenJDK Runtime Environment (build 1.8.0-292-b10)
OpenJDK 64-Bit Server VM (build 25.71-b10, mixed mode)

and works just fine

@irwsrs Could you be more specific?

I'm seeing this issue as well, on both windows WSL (Ubuntu OpenJDK) and Windows Java:
