Ralph Goers updated LOG4J2-2956:
--------------------------------
Description:
Assumptions:
# Application is a Spring Boot app.
# {{It is configured to use spring-boot-starter-log4j2}}
{{There is a log4j2.cfg.xml provided through logging.config property and it is
working fine. It contains following part:}}
{noformat}
<DynamicThresholdFilter key="X-Log-Level" onMatch="ACCEPT"
onMismatch="NEUTRAL">
<DefaultThreshold>INFO</DefaultThreshold>
<KeyValuePair key="DEBUG" value="DEBUG" />
<KeyValuePair key="TRACE" value="TRACE" />
</DynamicThresholdFilter>{noformat}
{{However when dependency log4j-spring-cloud-config-client is added application
does not start with following exception:}}
{noformat}
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize

{noformat}
First of all I have no idea what is missing. Without mentioned dependency
application startup is correct. Also, removing DynamicThresholdFilter solves
the problem as well.
Second of all it seems that exception message is somewhat broken, because it
does not say anything about what class is missing. I've tried to debug this,
but class ContextDataFactory is pretty hard to debug. Fix in exception message
should ease the hunt.
