Rule: Printf-style format strings should not lead to unexpected behavior at runtime (squid:S2275)

Version: Sonar 5.1.2, Java 3.4 plugin (Yes, I know there is already the 3.6 update but I didn't find anything about this rule in the release notes)

Steps to reproduce:

Analyze following code with the rule enabled:

String.format("%1$s %1$s", 1);

Says "Not enough arguments".

Hey Oliver,

Thank you for your feedback! There is indeed a problem with the implementation of the rules.

I created the following JIRA ticket to handle the issue: https://jira.sonarsource.com/browse/SONARJAVA-1334
