In my experience, to use java reliably, you need to have JAVA_HOME set to the jdk/jre directory. AFAIU you, you are running Sun JVM to compile AS and tests but you are running it with JAVA_HOME set to the openjdk location. Is that correct? I don't think that can work properly. It could if you have -Djava.home=<jdk.path>/jre. But in this case wouldn't it be easier to just set -Djunit.jvm ?
