emopers opened a new pull request #298: Synchronize before looping over synchronized collection URL: https://github.com/apache/logging-log4j2/pull/298 In StatusConfiguration.java, `errorMessages = Collections.synchronizedCollection(new LinkedList<String>())` is iterated over without synchronization. According to [Java API](https://docs.oracle.com/javase/6/docs/api/java/util/Collections.html#synchronizedCollection%28java.util.Collection%29), it is recommended that user manually synchronizes each iteration over the synchronized collection to reduce non-determinism. This pull request improved the condition by synchronizing a loop which loops over the synchronized collection.
