Hi
I'm not ususally a Java developer (more into C, C++), so please bear with me.
Just found out that compiling with jdk-9.0.4 does not work fully.
[ERROR] COMPILATION ERROR :
[ERROR] /C:/Users/Markus/git/openpnp/src/main/java/org/openpnp/machine/reference/signaler/SoundSignaler.java:[18,17] package sun.audio does not exist
Strangely I can still start the build. Must be some delayed class loading magic :).
Some Test errors too, however I can't reproduce them at the moment(?).
When I figured out to install jdk-1.8.0_162 and how to activate it in Eclipse (illogically under "Window"/"Preferences"), it warns:
/openpnp/src/main/java/org/openpnp/machine/reference/signaler/SoundSignaler.java:[18,17] sun.audio.AudioPlayer is internal proprietary API and may be removed in a future release
The errors go away, all tests pass.
Just wanted to point this out as the doc says "requires Java 8 or higher":
https://github.com/openpnp/openpnp/wiki/Developers-Guide#jdk-or-jre-8
Again thanks for all the great work!

Hi,
More information on this can be found here: https://bugs.openjdk.java.net/browse/JDK-8050465
I guess we should remove that code and replace the sun.audio interface. I created an issue on Github:
Best, Friedrich

Several things is not working on Java9. It compiles and just not works
because mostly
the reflexion interface have changed and as result, old code don't works.
Use java jdk8 for compiling.

Just for others to know, a little follow up:
If you installed JDK9 (on Microsoft Windows) and want to go back to JDK8 without removing JDK9, setting the environment variable %JAVA_HOME% to the JDK 8 path will make sure that your OpenPNP is built using JDK8 but it will still be run unter JDK9!
You need to also change the %PATH% environment variable to point to %JAVA_HOME%\bin. There is normally a fixed path (a linked directory) set that still points to JDK9.
Running under JDK9 will create problems. For instance you can't start the Computer Vision Pipeline editor:
