----------------------------------
Summary: Log4J2 not finding core Log4J2Plugins.dat when a custom
appender is present
Key: LOG4J2-752
URL: https://issues.apache.org/jira/browse/LOG4J2-752
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.0
Environment: RHEL 6
Netbeans 7.4
Java 1.7.0u45
Reporter: Zachary Boe
I'm working on a GUI that needs to be webstart capable. I have a custom
appender that I use to capture logging entries in memory so they can be
displayed on a Swing panel for the user. Everything runs fine when I run it
straight from the IDE, but things get wonky when I try to build the jars and
run with the "java -jar" incantation.
In short, with the webstart option *on* and when the custom appender is present
(in a package in the src/ folder, not even referenced anywhere else in code or
in log4j2.xml), Log4J2 will fail to find the Log4J2Plugins.dat file in the
log4j2-core jar, and will subsequently fail to find any other appenders/loggers
besides my custom one. Upon removing the package with the custom appender,
Log4J2 will find it's own .dat file and everything is fine.
With the webstart option *off* in the netbeans menu (which all it seems to do,
by looking a diff, is remove the "Codebase: *" line from META-INF/MANIFEST.MF),
the custom appender and log4j2 work in harmony.
I have the log4j2-core and log4j2-api jars added as compile-time libraries. I
can unzip the log4j2-core jar and my application jar after everything is built
and find the respective Log4J2Plugins.dat files in each jar.
I have example netbeans projects which I can hopefully attach at request to
demonstrate this problem. I feel I've done a great bit of troubleshooting to
narrow down this problem. Hopefully this can be resolved, or I may have to
downgrade to log4j, since it's known working on other projects in house.
Thanks for your help!
