Yes you can, but what is in the string is not a valid groovy snippet 
while the entire snippit outside of the string as a while is valid 
groovy (and java if properly placed in a class and method).  The error 
comes from evaluating a program that looks like

a='

Which in and of itself is grammatically invalid for Groovy.

And since the original snippet produces no output anyway and nothing is 
reported in the exception (not even a 'e.printStackTrace()') whether or 
not the string holding the script is valid or not no output would result 
anyway.
