It shouldn't, but if it does you can change the java alternatives back
to openjdk-7 with the update-java-alternatives utility [0] to switch the
alternatives for all JRE executables not just /usr/bin/java.

 # update-java-alternatives -s java-1.7.0-openjdk-amd64

You should pass JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 to
Whitebox to have it use the non-default JRE and leave the other
applications to use the default JRE configured in the alternatives system.

Please ignore the Ubuntu Java documentation [1], it says to use
update-alternatives --config java, but this is inferior to
update-java-alternatives.
