>             Project: Groovy
>          Issue Type: Bug
>          Components: parser-antlr
>            Reporter: Jochen Theodorou
>            Assignee: Daniel Sun
>            Priority: Major
>             Fix For: 2.6.0-alpha-1
>
>
> {code}​println 09​{code}
> This code will cause a NPE, because it will be evaluated as println 0 9, 
> which is evaluated as println(0).9. This happens because the leading zero 
> introduces an octal, but 09 is no octal. The parser no falsely accepts 0 as 
> valid number and does not recognize that 09 is supposed to be a single number 
> anymore.
> The expected behaviour is a compile time failure.
> Daniel, can we fix that in parrot?
