instantbibi does not start with openjdk 8

[mwiens]

while calling

ant instant.environment && ant install.wizard

it throws:

BUILD FAILED

Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-8-openjdk-amd64/jre"

It seems that oracle Java is required.

I've tested the installation with both – openJDK 8 and Oracle JDK 8 – it works only with the last one.

Well, it could be the case that it just works with oracle. The ci tests are also running with oraclejdk
