I am trying to use Log4j2 in my webapp which runs in Tomcat which has its
Security policy enabled.
While initial load of Log4j2 via Commons logging bridge I keep getting -
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.logging.log4j.core.lookup.JmxRuntimeInputArgumentsLookup
I have narrowed it down to the initialisation code of the class
static {
final List<String> argsList =
ManagementFactory.getRuntimeMXBean().getInputArguments();
JMX_SINGLETON = new
JmxRuntimeInputArgumentsLookup(MapLookup.toMap(argsList));
}
Where this code needs particular security permission to be enabled. Any
idea which permission does this need in the Tomcats catalina.policy file?
Following is the StackTrace -
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.logging.log4j.core.lookup.JmxRuntimeInputArgumentsLookup
