Use of Hyperloop addEventListener throws "unknow exception".
Pushing "PUSH" button should show "pushed" dialog.
After some investigation, I found that at some point of Titanium SDK update, we updated uglify-js but it looks like it contains breaking changes. Uglify-js doesn't resolve constructor (init property of AST_Symbol on its scope analyzer. It looks like there was breaking changes there, maybe from uglify-js 2.8.x, because I saw uglify-js 2.7.x (Titanium SDK 6.1.0.v20170315131319) worked fine.
