This Cask makes minor modifications to the JRE to prevent issues with
packaged applications, as discussed here:

  https://bugs.eclipse.org/bugs/show_bug.cgi?id=411361

If your Java application still asks for JRE installation, you might need
to reboot or logout/login.

Installing java means you have AGREED to the license at

Reading the Java Cask, I could realize that there is no call to the EOS.undent method.
But, searching a bit in the brew repositories, I found this issue comment, that made me realize that there is a call to the EOS.undent method in the older java Cask that was installed some time ago (/usr/local/Caskroom/java/.metadata/1.8.0_141-b15,336fa29ff2bb4ef291e347e091f7f4a7/20170719070345.780/Casks/java.rb).

I think the issue is happening due to this.

[juanmbellini]

Ok, I could fix it by removing the call to the undent method in the java.rb file in the .metadata directory. Once removed, I executed brew cask uninstall java && brew cask install java. After this I got last java version installed.

However, it would be great that brew could handle these cases in which the installed versions of the packages are outdated.

[vitorgalvao]

Yes, that is the correct solution for now. Closing as duplicate.
