Mike commented on LOG4J2-3257:
------------------------------
So I know that exception is typically when Java can't resolve the difference in
two methods. However, I have been running .15 and .16 fine, and I can switch
back and forth between those two, the problem only crops up on .17 and was
wondering if there was any insight.
> MDC class in 2.17.0 has multiple "put" methods
> ----------------------------------------------
>
> Key: LOG4J2-3257
> URL: https://issues.apache.org/jira/browse/LOG4J2-3257
> Project: Log4j 2
> Issue Type: Bug
> Components: log4j 1.2 emulation
> Affects Versions: 2.17.0
> Reporter: Mike
> Priority: Major
>
> We use MDC.put for a variety of things. With the 2.17 version, it appears
> there is a bug.
> When including the jar from maven, we can see the following:
>
> {code:java}
> private MDC() {
> }
> public static void put(final String key, final String value) {
> localMap.get().put(key, value);
> ThreadContext.put(key, value);
> }
> public static void put(final String key, final Object value) {
> localMap.get().put(key, value);
> ThreadContext.put(key, value.toString());
> } {code}
> Java is very unhappy when trying to call this, and causes problems in our
> application.
> The error we are getting is:
> {code:java}
> SEVERE: Servlet.service() for servlet [default] in context with path [] threw
> exception [Filter execution threw an exception] with root cause
> java.lang.NoSuchMethodError:
> org.apache.log4j.MDC.put(Ljava/lang/String;Ljava/lang/String;)V {code}
> I have reverted back to 2.16.0 for the time being and we aren't having
> problems.
