Unable to install java8 with homebrew : <p>Installing <code>java8</code> with Homebrew seems to no longer be working. After running:</p>

<pre><code>brew install caskroom/cask/java8
</code></pre>

<p>I get the following error:</p>

<pre><code>Error: Cask 'java8' is unavailable: '/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks/java8.rb' does not exist.
</code></pre>

<p>Simply doing:</p>

<pre><code>brew cask install java8
</code></pre>

<p>Errors out with:</p>

<pre><code>Error: Cask 'java8' is unavailable: No Cask with this name exists.
</code></pre>

<p>This seems like a recent development because I remember installing it this way a few months ago. Any suggestions on how to properly install <code>java8</code> on MacOS nowadays?</p>
