Roland Weiglhofer commented on LOG4J2-389:
------------------------------------------
After I made log4j-core-osgi-reduced lightweight, I get following exception:
Exception in thread "Log4j2-Test" java.lang.NullPointerException

What I have missed?

> Key: LOG4J2-389
> URL: https://issues.apache.org/jira/browse/LOG4J2-389
> Project: Log4j 2
> Issue Type: Improvement
> Components: API, Core
> Affects Versions: 2.0-beta9
> Environment: Maven
> Reporter: Roland Weiglhofer
> Labels: Maven, dependencies, optional
>
> Required is a lightweight version without database and http stuff, so I do
> not need to install libraries, which I do not need. All the (transitiv)
> log4j2-dependencies together are much bigger than my own application. This is
> a realy big drawback of log4j2! log4j-core-osgi-reduced depends on log4j-core
> and thus, on all transitiv dependencies, although they are declared as
> "optional".
> Thanks & Regards
