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?

@George There aren't any other related files there. I've tried searching through /etc but haven't found anything else updating PATH.

@George I'd prefer not to actually remove it if possible. I just want to temporarily swap to openjdk and then swap back again. It seems likeupdate-alternativeswas designed for 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.

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.
