David Johle closed LOG4J2-917.
------------------------------
Resolution: Not a Problem
Gah! There was a stray JAR file in my classpath that was interfering.
> NoSuchMethodError: o.a.l.l.core.config.Configuration.getStrSubstitutor()
> ------------------------------------------------------------------------
>
> Key: LOG4J2-917
> URL: https://issues.apache.org/jira/browse/LOG4J2-917
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1
> Environment: Linux x86-64, JDK 1.6.x
> Reporter: David Johle
> Priority: Minor
> Labels: configuration, exception, startup
>
> I have a custom RolloverStrategy that I have been using since the early
> betas. I am trying to bump up to v2.1 now, and when I start up my
> application I receive a surprising NoSuchMethodError for a method that for
> sure exists.
> In fact, my code is quite similar to the DefaultRolloverStrategy, and the
> particular call that is throwing the exception is exactly as it's used in the
> default scenario: config.getStrSubstitutor()
> The "SharedFileRolloverStrategy" is my class, it deals with rollovers of
> shared logs in a cluster with shared filesystem. Here is a bit of the debug
> logs during startup, including some output I've added just prior to the
> offending call, along with the exception:
> 2014-12-08 15:24:18,164 DEBUG Calling createStrategy on class
> org.apache.logging.log4j.core.appender.rolling.SharedFileRolloverStrategy for
> element SharedFileRolloverStrategy with
> params(Configuration(/path/to/log4j2.xml))

> I have run this under a debugger, and it is indeed an XmlConfiguration object
> as indicated. I see that extends AbstractConfiguration where the actual
> getStrSubstitutor() method is implemented. I even looked at the strings in
> the .class file in the JAR I downloaded and see references to that method.
> I'm at a loss as to why it is saying it does not exist.
