-------------------------------------
I am not really sure how to do that. The actual git repository we use is hosted
by the ASF, not at github, so whatever is there is some kind of mirror.
Can you do a git diff and attach the patch?
> Incorrect Line Number in location information
> ---------------------------------------------

> Key: LOG4J2-1028
> URL: https://issues.apache.org/jira/browse/LOG4J2-1028
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.3
> Environment: Java 1.8.0_45 64-bit
> Maven 3.3.1
> Windows 7
> basically any...
> Reporter: Stefan Leonhartsberger
>
> When enabling location information in Log4j2
> The line numbers of the log records are incorrect
> as they are only taking into account the first time in the stacktrace where
> the
> class in question (FQCN) was called
> This however may not be accurate as the class may call methods within itself
> adding to the stacktrace - these are not considered when gathering location
> information within Log4jLogEvent.
> An example stacktrace:
> {code}
> stackTrace = {java.lang.StackTraceElement[18]@4612}
> 0 = {java.lang.StackTraceElement@4617}
> "java.lang.Thread.getStackTrace(Thread.java:1552)"
> 1 = {java.lang.StackTraceElement@4618}
> "org.apache.logging.log4j.core.impl.Log4jLogEvent.calcLocation(Log4jLogEvent.java:386)"
> 2 = {java.lang.StackTraceElement@4619}

> 3 = {java.lang.StackTraceElement@4620}
> "org.apache.logging.log4j.core.async.AsyncLogger.logMessage(AsyncLogger.java:252)"
> 4 = {java.lang.StackTraceElement@4621}
> "org.apache.logging.log4j.spi.AbstractLogger.logMessage(AbstractLogger.java:738)"
> 5 = {java.lang.StackTraceElement@4622}
> "org.apache.logging.log4j.spi.AbstractLogger.logIfEnabled(AbstractLogger.java:708)"
> 6 = {java.lang.StackTraceElement@4623}
> "com.test.logging.factory.Log4j2Factory$Log4J2CatsLogger.log(Log4j2Factory.java:106)"
> 7 = {java.lang.StackTraceElement@4624}
> "com.test.agent.configuration.Configuration.setPttId(Configuration.java:1079)"
> 8 = {java.lang.StackTraceElement@4625}
> "com.test.agent.configuration.Configuration.loadDefaultConfiguration(Configuration.java:323)"

> 17 = {java.lang.StackTraceElement@4632}
> "com.test.agent.AgentMain.main(AgentMain.java:86)"
> {code}
> Expected Line Number: 1079
> Received Line Number: 302
> Reason is that the stack is iterated from the wrong direction - i=17.
> (starting with i=0 would result in the correct behaviour.
