log4j2 JsonLayout not loading

[jordansissel]

I was helping a user out with some Elasticsearch log processing, and I recalled that Logstash offers JsonLayout for its logs, and until #8786 is resolved, I was hoping to offer a workaround.

When attempting to use this in Elasticsearch, it crashes on startup with an exception. I searched existing issues which seem to point to a necessary security policy, but my error isn't identical and even with the workaround security policy (I think?) loaded it still fails.

Tested with:

• Elasticsearch 6.4.2
• openjdk version "1.8.0_181"
• Fedora 28

log4j2.properties:

appender.console.layout.type = JsonLayout
appender.console.layout.compact = true
appender.console.layout.eventEol = true

Elasticsearch output:

@jordansissel sorry, I'd like to close this issue as a duplicate of issue you've mentioned.

From my end I try to raise a problem again.
