#14058.

[bsbodden]

I deleted the directory /opt/homebrew-cask/Caskroom/java7 for the offending cask. I couldn't uninstall it via brew cask uninstall (even with --force). Now brew cask list works. This is a great tool and a superb advance over Apple's traditional install route it just needs a little polishing on the error messages and handling of some exceptions. (I assume is all due to the recent changes on brew cask)

Thanks @vitorgalvao !
