-----------------------------------
Summary: LoggerConfig.getProperties() should not allocate on each
call
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
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.
