Description

An exception occurs in Groovy if the groovy file contains the character #.

This happens on linux systems where a script that starts with a # will result in an error:

Exception in thread "main" java.lang.ClassFormatError: Illegal class name "" in class file 

simply doing this:

groovy /path/#myfile

will produce this error.

This is a regression caused by GROOVY-6641
