Subject [jira] [Created] (GROOVY-8216) invalid octal split into two arguments
Date Thu, 01 Jun 2017 18:31:04 GMT
Jochen Theodorou created GROOVY-8216:

             Summary: invalid octal split into two arguments
                 Key: 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?
