Regex crashes rather than failing gracefully

[Calem Bendell]

Exception in thread "Animation Thread" java.lang.IllegalStateException: No match found
    at java.util.regex.Matcher.group(Unknown Source)

Error occurs when making regex errors for a function name input. My instance of error was + void renderFrame())

Better result may be graceful failure.

Can you give ~5 more calls of the stack trace, please? The information about where the call was made from is missing :)

This issue is already fixed (#93).

Your branch is behind. Once you update it to the current state it will work :)
