Good catch. I was misled by the docs [1].

Subject: Re: [FlexJS] String.match()

Both Flash and JS engines automatically convert to RegExp. I had not realized 
that at first.

It seems that the only difference between the Flash engine and JS engines is 
what happens when constructing a RegExp object from invalid input. Flash 
matches nothing, while JS throws an error.

By just wrapping the call in a try/catch, that seems to resolve the issue.

I added the trace because I think it’s bad practice to use strings instead of 
RegExp because it can lead to unexpected results and a new RegExp instance 
needs to be constructed every time.
