How do I stop oracle JDK from hijacking PATH and breaking update-alternatives?

I installed oracle jdk on ubuntu 14.04. Now I want to toggle back to openjdk:

sudo update-alternatives --config java
sudo update-alternatives --config javac

But it doesn't work. It seems oracle's jdk somehow keeps adding itself to my $PATH:

...:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin:...

I've found and killed /etc/profile.d/jdk.csh, but there seems to be a failsafe. The audacity!!

How can I fix this?

I think you are on the right track by removing /etc/profile.d/jdk.csh and /etc/profile.d/jdk.sh. You just have to re-login or reboot so that the PATH changes have effect.
