Author: Ceki Gulcu <ceki@qos.ch> Date: 2015-03-25 (Wed, 25 Mar 2015) Changed paths: M logback-classic/src/main/java/ch/qos/logback/classic/spi/LoggingEvent.java M logback-classic/src/test/java/ch/qos/logback/classic/log4j/XMLLayoutTest.java Log Message: ----------- prevent access to LoggingEvent's CACHED_NULL_MAP This prevents developers from attempting to modify event's mdc map. For example by invoking event.getMDCPropertyMap().put("k", "v"); This fixes LOGBACK-1063 by ricochet.
