Subject [jira] [Created] (LOG4J2-963) Location Info is not rigth
Date Thu, 26 Feb 2015 12:46:04 GMT
Antonio Jesus Simon Escanez created LOG4J2-963:

             Summary: Location Info is not rigth
                 Key: LOG4J2-963
                 URL: https://issues.apache.org/jira/browse/LOG4J2-963
             Project: Log4j 2
          Issue Type: Bug
          Components: Pattern Converters
         Environment: production
            Reporter: Antonio Jesus Simon Escanez
            Priority: Minor

This bug is for Log4j 1.2.17 and I am not sure if it is also in 2.0. When org.apache.log4j.spi.LocationInfo
get information of the class who write the log (looking for in the stack trace), there is
two things:

1. Performance. In the constructor LocationInfo(Throwable t, String fqnOfCallingClass) is
better walk from index 0 to straceTrace.length - 1 instead of in reverse. The log wrraped
class is very much nearest of index 0 than index straceTrace.length - 1.

2. Bug. If the log wrapped class twice appears twice o more times in the stacktrace, you always
get the first, when the right would be get the last. For this reason, you have to walk from
index 0 to straceTrace.length - 1 instead of in reverse.


P.D.: Please, it would be possible you generate log4j-1.2.18 with this fix? Thanks.
