Hi,

When starting the Openhab 1.8.3 runtime, I get the same error repeating every 10 seconds. I’m trying to run the Openhab demo as a first attempt with Openhab. I’ve tried running the runtime using both start.sh and start\_debug.sh and I’m always getting the same error. No log file is created in /opt/openhab. My hardware is a Odroid C2.

Java version:

```csv
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-2ubuntu0.16.04.2-b14)
OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode)

```

Error on CLI using start\_debug.sh:

```csv
12:27:59.765 [ERROR] [.o.m.c.i.folder.FolderObserver:105] - An unexpected exception has occured
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.xtext.resource.XtextResourceSet$1

```

Tell me if you need anything else!

Thanks,

Jeffrey

Please change your Java version to Oracle.

I’m not sure to understand what this means… Can you provide a link, or instructions to download it?

Thanks!

I didn’t know about different vendor version.

Even with the oracle version I’m still getting the same error. I’ve installed the product:  
Linux ARM 64 Hard Float ABI (jdk-8u121-linux-arm64-vfp-hflt.tar.gz)  
from this link  
[http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)  
since my odroid c2 is running a ARM 64bits.

Java version:

```csv
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

```

Is there something I missed?

Thanks!

It seems that the problem was caused by wrong access permissions on /opt/openhab folder!
