Syntax error with file that has OK syntax with MRI 2.2

[madis]

The exception SyntaxError in /Users/madis/.rvm/gems/jruby-9.0.0.0.pre1/gems/hairtrigger-0.2.12/lib/hair_trigger/builder.rb:468: syntax error, unexpected tLABEL_END occured when a dependency I am using was tried to get loaded by jruby-9.0.0.0.pre. When checking with MRI 2.2.0 syntax was considered ok:

Line reported to be erroneous: https://github.com/jenseng/hair_trigger/blob/0e4c937ad9e1ed48797d1e376d241bdc61dfa140/lib/hair_trigger/builder.rb#L468

A reduced case:

cond ? x + ')': ''

The parser seems to think the ')': is a hash label rather than being separate tokens ')' and ':' (for the ternary).

Parser bug for @enebo.
