>             Project: Karaf
>          Issue Type: Bug
>    Affects Versions: 4.1.1
>            Reporter: Christopher Lockard

>
> When including class and line in the console logger pattern a NPE is thrown when doing a log:tail or log:display. 
> This appears to be a result of the KarafLogEvent not keeping the location information and the PatternParser not checking if location information is available before trying to use it. 
> This is the pattern in org.apache.karaf.log.cfg that causes the NPE
> pattern = %d{ABSOLUTE} | %-5.5p | %-16.16t | %-40.40C %4L | %-20.20X{bundle.name} | %m%n
> This is the exception thrown
> Exception in thread "pool-28-thread-1" java.lang.NullPointerException
