> Hi,
> I am reporting the following bug as I am not able to ascertain from the web if what I am facing is a consequence of desired intent.
> Using groovy shell to execute the following groovy script snippet fails at compilation phase when executing the script through java. I am using Jre1.7
> {code:java}
> public static void main(String[] args) throws Exception, IllegalAccessException {
>     Object evaluate = new GroovyShell().evaluate("\"abcd\".length() == .34");
>     System.out.println("result: " + evaluate); 
> }{code}
>  In the above snippet, If I replace *.34* with *0.34* then the script execution works as expected.
> Exception reported is as follows
> {code:java}
> Exception in thread "main" org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Script1.groovy: 1: unexpected token: . @ line 1, column 20.
> "abcd".length() == .34
> ^
