title: no stack', reason: 'Unhandled JS Exception: Invalid regular expression: invalid group specifier name
body: <p>My app will not boot, it will break with the exception:</p>
  
  <pre><code>Invalid regular expression: invalid group specifier name
  
  no stack

  </code></pre>
  
  <p>I found that in iOS or android, if I enabled live javascript debug, then the problem will not occur, but why?</p>
  
  <p>The same error I got on xcode and android:</p>
  
  <pre><code>no stack', reason: 'Unhandled JS Exception: Invalid regular expression: invalid group specifier name
  </code></pre>
  
  <p>I have no idea where to dig? or where to debug?
  Any one can help?</p>
