Andrejus Chaliapinas commented on LOG4J2-2266:
----------------------------------------------
Matt - I've double-checked and used also verbose class loading and could
confirm that there are no duplicate log4j-api jars in my classpath. And that
PropertiesUtil/StatusLogger/LogManager are all loaded from same jar.
I think Ralph has summarized quite well what could be root cause in this case
and that some similar previous fix is needed here. If you could provide some
patch to try - I could try that.
> Log4j2 throws NoClassDefFoundError in Java 8
> --------------------------------------------
>
> Key: LOG4J2-2266
> URL: https://issues.apache.org/jira/browse/LOG4J2-2266
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.10.0
> Reporter: Andrejus Chaliapinas
> Priority: Major
>
> During Unit Tests run using JDK 8 and Log4j2 v2.10.0 - getting this as part
> of exception stack:
>
> java.lang.NoClassDefFoundError: Could not initialize class
> org.apache.logging.log4j.util.PropertiesUtil
> at
> org.apache.logging.log4j.status.StatusLogger.<clinit>(StatusLogger.java:71)
> at org.apache.logging.log4j.LogManager.<clinit>(LogManager.java:60)
>
> and issue seems to be somehow related to what is reported so far against JDK
> 9 here: LOG4J2-2129.
>
> If some patch on top of v2.10.0 is available to test - please let me know
> where to download it from.
>
> While running same UTs with same JDK 8 and v2.8.2 - issue is not observed.
>
> And question which I have here - why not introduce JDK8 compatibility runtime
> mode while things with JDK9 are not yet that stable? So it could continue use
> same logic as of v2.8.2 around that ServiceLoader and not cause side effects.
