Daniel Sun commented on GROOVY-8216:
------------------------------------
Jochen, I think it can be fixed in Parrot ;)
> invalid octal split into two arguments

> Key: GROOVY-8216
> URL: https://issues.apache.org/jira/browse/GROOVY-8216
> Project: Groovy
> Issue Type: Bug
> Components: parser-antlr
> Reporter: Jochen Theodorou
> Assignee: Daniel Sun
>
> {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?
