Installing specific major Java JDK versions on OS X via Homebrew
Note that if you install the new Java update Version 8 Update 66 is the latest following the instructions on my blog post, the previous Java version is not removed or overwritten. If you run into issues, you can simply remove the folder where the update was installed, and OS X should automatically start using the previous Java version. I think the recommended way to ship Java applications is to bundle the JRE with the application. There are many applications that use Java unbeknownst to the user because it is bundled in the application, and does not require the user to install Java on their computer.
When the specific path to the library changed, some older apps stopped working. Oracle increments the version number when there are potentially application-breaking changes. There is no guarantee that apps that run on Java 6 will run on Java 7, let alone Java 8. It is up to the application developer to update their code if they wish to use the latest version of Java. It may have been nice of Oracle to add those links, to increase backwards compatibility, but it is not their responsibility, and in my opinion, should not be including them.
Thanks for the excellent posting on installing the JDK onto a mac. I am totally new to the mac environment and this posting really helped. I tried to follow the other posting for the JRE but ended up not being able to use it for apps like LibreOffice. But the idk post worked like a champ. Again Thanks. Oliver, thank you for your help with this. I have a question.
