             Summary: NPE when location information is included in console logging pattern
                 Key: KARAF-5124
                 URL: https://issues.apache.org/jira/browse/KARAF-5124
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.1.1
            Reporter: Christopher Lockard
             Fix For: 4.1.2


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
