NullPointerException during startup
-----------------------------------

                 Key: OFBIZ-1065
                 URL: https://issues.apache.org/jira/browse/OFBIZ-1065
             Project: OFBiz
          Issue Type: Bug
          Components: framework
    Affects Versions: SVN trunk
            Reporter: Oleg Andreyev
            Priority: Minor


Since rev.541008 log4j AsyncAppender trow a NullPointerException during OFBiz startup.

Exception in thread "Dispatcher-Thread-1" java.lang.NullPointerException
        at java.lang.String.lastIndexOf(String.java:1654)
        at java.lang.String.lastIndexOf(String.java:1636)
        at org.apache.log4j.spi.LocationInfo.<init>(LocationInfo.java:119)

.java:191)

        at org.apache.log4j.AsyncAppender$Dispatcher.run(AsyncAppender.java:578)

        at java.lang.Thread.run(Thread.java:595)

Solutions are:
1. Remove tag <param name="blocking" value="false"/> from async appender section or make it value true. This reverts logging to sync mode.
2. Migrate to log4j 1.12.15 (http://issues.apache.org/bugzilla/show_bug.cgi?id=41186)

David E. Jones commented on OFBIZ-1065:
---------------------------------------

Andrew Zeneski can comment more on this as he researched this and made the change.

It is important though that blocking is false because otherwise there were deadlocks in high volume logging with multiple threads (as is the norm for OFBiz).
