Hi, I have the same issue with my test. It's easily reproducible with the conf : 

{code:title=log4j2.xml|borderStyle=solid}
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="warn">
    <properties>
        <property name="filters">org.junit,org.apache.maven,org.eclipse,sun.reflect,java.lang.reflect</property>
    </properties>
    <appenders>
        <console name="console" target="SYSTEM_OUT">
            <patternLayout pattern="%d{HH:mm:ss,SSS} [%t] %-5level [$${date:yyyyMMdd.HHmmSS}]
%logger{1}.%method:%line - %msg%n%rEx{filters(${filters})}" />
        </console>
    </appenders>
    <loggers>
        <root level="warn">
            <appenderRef ref="console" />
        </root>
    </loggers>
</configuration>
{code}

In the example I use {noformat} $${date:xxx} {noformat} but in real, I use a personal lookup.

, int , int , List<String> ) @ Line 816-817 @new String(chars,   offset, length). The
String should be new String(chars,				offset, length + lengthChange) this is because of the
character deletion that might have happened for '$".
