Hello, I have created a GitHub PR (#476) <https://github.com/apache/logging-log4j2/pull/476> addressing LOG4J2-3004 JsonTemplateLayout plugin support <https://issues.apache.org/jira/browse/LOG4J2-3004>. I needed to make a small (backward-compatible) change to TypeConverterRegistry and I have some troubles with AsciiDoc. These and more are mentioned in the description of the PR. I will appreciate it a lot if somebody could review the changes.
Cheers!
