------------------------------------
Until 3.0.1 is released, workaround can be to name identifier with a dot, e.g.
workaround.myCheckIdentifier
> StringIndexOutOfBoundsException in RuleUtil

> Key: MCHECKSTYLE-344
> URL: https://issues.apache.org/jira/browse/MCHECKSTYLE-344
> Project: Maven Checkstyle Plugin
> Issue Type: Bug
> Components: checkstyle:check
> Affects Versions: 2.17
> Reporter: fdvxxii
> Assignee: Guillaume Boué
> Priority: Major
> Fix For: 3.0.1
>
>
> {{RuleUtil}} has a bug at line 95:
> {code}
> final int end = eventSrcName.lastIndexOf('.');
> eventSrcName = eventSrcName.substring(0, end);
> {code}
> This code leads to a StringIndexOutOfBoundsException if the variable does not
> contain a period. I don't know if its a convention to have a period in that
> string, but either way the error message should me more expressive.
