CPU usage on armbian with open JDK

I’ m testing OpenHab on a Cubieboard ARM Motherboard, running Armbian OS and open JDK (I know that it is tested with Raspberry and Oracle Java). Armbian is based on Debian Jessie, and java version is…

Java version “1.7.0_95”
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb8u1)
OpenJDK Zero VM (build 24.95-b01, mixed mode)

OpenHab runs from a folder inside myHome folder and it is running continuously without problems. But every 5 or 6 days suddenly the process Java-Dosgi.clean=true -Declipse.Ignoreapp=true … starts to consume the 100% of CPU power. Consuming all the CPU resources the server performance decreases and I have to kill the start.sh process, which is the father process and restart OpenHab

Is there any idea, for a solution to the above problem.
The attached file shows the processes tree after OpenHab restart.

Not only is it tested with Oracle Java, it is known to work better. There are known problems when using OpenJDKb which is why it is not recommended.

So you think that OpenJdk causes the problem which I described?

It is a distinct possibility. The behaviour you are describing sure sounds like a JRE issue more than OH issue.
