Christopher Lockard created KARAF-5124:
------------------------------------------
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
