highlight not working anymore

the ansi color support is broken since version 2.9.0 I used to setup my pattern like this:

<PatternLayout pattern="%d{DATE} [%t] %highlight{%-5level}{FATAL=bright red, ERROR=red, WARN=yellow, INFO=white, DEBUG=bright blue, TRACE=green } %logger{36} (%F:%L) - %highlight{%msg%n%throwable}{FATAL=bright red, ERROR=red, WARN=yellow, INFO=white, DEBUG=bright blue, TRACE=green }"/>

but when I updated recently from 2.8.2 to version 2.11.0 it did not work anymore. I tried all versions backwards to 2.8.2 but all versions above 2.8.2 wont work with highlighting...
