Health check fails, missing dependency?

[markreg]

When I curl -v "localhost:port/about/health" returns a 500. Is something missing from the dependencies? I installed JRE 8.

I tested this in our test deployment with latest versions and I cannot reproduce it. It should be something on your side and the way you are deploying.

[markreg]

java -v outputs:

java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

I'm not sure what else it could be since this is a fresh VM for JVB with nothing else on it. Is java.awt.toolikit something I need to install separately?

[damencho]

Nope this is standard class, I think its even exists in jre-headless. Not sure what can be the problem ... Is this ubuntu or debian which version? Are you installing and running from deb packages?

[markreg]

Got it to work, I had installed the oracle-java8-installer but not default-jre. For future reference, on ubuntu, should java be installed from apt-get or is there a standalone deb package that is recommended?

[damencho]

As current ubuntu LTS 14.04 doesn't have openjdk-8 we install it from ppa: add-apt-repository -y ppa:openjdk-r/ppa apt-get update apt-get install openjdk-8-jdk
