> Key: LOG4J2-1542
> URL: https://issues.apache.org/jira/browse/LOG4J2-1542
> Project: Log4j 2
> Issue Type: Bug
> Components: API
> Affects Versions: 2.6.2
> Environment: Array length logic causes throw
> java.lang.ArrayIndexOutOfBoundsException
> Reporter: Rogério Lecarião Leite
> Priority: Critical
> Labels: easyfix
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> This error is reproducible when method fomarTo of the class
> ParameterizedMessage is invoked.
> This root cause is the method init of same class where is invoked, in the
> this.indices is initializaded with messagePattern.length() >> 1 run to equals
> zero because that messagePattern.length() is 1 (string with one character).
> I used File Appender in my XML config and I wrote my code with
> logger.trace("a").
> My PatternLayout used is pattern="%m" (simplest).
