I've a heterogeneous Java installations, where I've installed some versions manually and others via the package manager. I wanted to have javac to change accordingly with java, so I had each java version with its own javac slave. I can't recall off the top of my head of whether I've removed javac own separate alternatives while doing so, but surly I don't have one as of now.
Now whenever I try to upgrade or even install another package, I got this error message appended at the end. I'm thinking of disabling the post-installation script, but I don't how to selectively disable it for java.
Solutions that I'm not for:
- Reverting to the previous behavior of having separate
java and javac alternatives
- Total dependence on some other version manager (I've got this solution recommend in a ruby answer).
