The non-free sun implementation of java (the official one) is not 
packaged, because sun does not permit that. The packages you see are 
help-packages to help you install the official version, which apparently 
doesn't work. You can download it manually from java.sun.com and install 
it in /opt if you can't figure out how to do it in another way.

If you don't know what package a file belongs to, do `dpkg -S 
/your/file`. Then you know what to remove. If you didn't install it with 
  a package manager, you can just remove it.
