Reproduce the error

• fork and clone JDL Studio
• in bower.json change from

"pegjs_parser": "https://raw.githubusercontent.com/jhipster/jhipster-core/v1.1.5/lib/dsl/pegjs_parser.js",

to (error occurs with versions 1.2.3 and 1.2.4)

"pegjs_parser": "https://raw.githubusercontent.com/jhipster/jhipster-core/v1.2.4/lib/dsl/pegjs_parser.js",

hint: can reference to local version, for example if jhipster-core and jdl-studio are cloned into same parent folder then reference is:

"pegjs_parser": "../jhipster-core/lib/dsl/pegjs_parser.js",

• bower install
• gulp build

Interesting... I'd rather not have a issue opened here for the JDL Studio though.
