It is possible to have multiple versions of java on the same machine. You can easily switch the system default java version:
sudo update-alternatives --config java
Note: Some programs rely on the $JAVA_HOME environment variable, which might differ from java -version. Run your program like this to avoid this problem: JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java /opt/your_program
