Almost the same technique as yesterday, but a much bigger timesaver this time. Most Linux distributions come with the open OpenJDK installed. This is fine for most things, but I’ve noticed that apps that are graphically complex (PyCharm for one) have some rendering issues and CPU usage is high.
You can install the Sun/Oracle Java instead, but this seems to be a pain to do from the download. There is another PPA for this:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installerIt still downloads all however-many-megabytes of installer, but it’s fire and forget. No need to un-install OpenJDK, they can coexist.

July 22, 2013 at 12:42amThe last time I used the above commands was to install the latest Nvidia drivers. After that the packet managed failed. I restored by delating most of what was there and updating mega gobs of stuff to get it back. Any comment?

August 12, 2013 at 6:04pmBrilliant! At last a quick and simple way to fix Java. My bank keeps changing the Java version required and I was struggling to get it to work for a couple of hours until I found this and had it sorted in 2 minutes.
PS Works with Mint 14 too

March 6, 2014 at 5:08pmCongratulations! You are a special man, and shared a very important solution for Java on Mint 15!!! My problem was the same of Alister (Internet Banking – Banco Itau). Writing from Sao Paulo, Brazil… Many thanks! Do you know if this works on Mint 16 Cinnamon?
