> Key: LOG4J2-1281
> URL: https://issues.apache.org/jira/browse/LOG4J2-1281
> Project: Log4j 2
> Issue Type: Improvement
> Components: Core
> Affects Versions: 2.5
> Reporter: Remko Popma

> Fix For: 2.6

>
> LoggerConfig.getProperties() is currently implemented as
> {code}
> public Map<Property, Boolean> getProperties() {
> return properties == null ? null :
> Collections.unmodifiableMap(properties);
> }
> {code}
> this creates a new {{UnmodifiableMap}} object for each call.
> We can wrap the {{properties}} field with {{Collections.unmodifiableMap}} in
> the constructor, so there is no need to do this on every call.
