@rgoers Could you please review this pull request?
I believe your original logic was broken when implementing LOG4J-1321
> NameAbbreviator skips first fragments
> -------------------------------------
>
> Key: LOG4J2-2365
> URL: https://issues.apache.org/jira/browse/LOG4J2-2365
> Project: Log4j 2
> Issue Type: Bug
> Components: Pattern Converters
> Affects Versions: 2.11.0
> Reporter: Eugene Zimichev
> Priority: Major
>
> When I use LoggernPatternConverter in beginning of my layout it outputs as
> expected
> {code:java}
> <PatternLayout pattern="%c{1.1.*} %date{HH:mm:ss.SSS} %-5level %-25thread|
> %msg%n%xThrowable"/>{code}
> {code:java}
> c.k.zoo.CuratorEnsembleProvider 16:48:13.175 INFO main | Connecting to
> ensemble on [localhost]:8080{code}
> However when I move converter to the end of the layout it stops abbreviating
> logger name parts.
> {code:java}
> <PatternLayout pattern="%date{HH:mm:ss.SSS} %-5level %-25thread| %c{1.1.*}
> %msg%n%xThrowable"/>{code}
> {code:java}
> 16:47:38.687 INFO main | com.kamagames.zoo.CuratorEnsembleProvider Connecting
> to ensemble on [localhost]:8080{code}
>
> I believe it's caused by code in NameAbbreviator which stops processing first
> pattern fragments when abbreviated string length is larger than current
> position in StringBuilder
>
> {code:java}
> for (int i = 0; i < fragments.length - 1 && pos < original.length(); i++) {
> pos = fragments[i].abbreviate(sb, pos);
> } {code}
