customFields in Logstash throws NullPointerException in Spring Boot

[clteich]

I'm encountering a problem with the logstashencoder in my spring boot project. If I'm using the logback configuration posted below, the application fails immediately with the following stacktrace. If I delete the customFields in the logstashEncoder, the application starts as intended.

The problem seems to originate from an update of the jackson-databind-dependency. We had an alarm from our dependency check, that the version 2.9.9 of this library has jackson-databind-2.9.9.jar: CVE-2019-14379, CVE-2019-14439.

Upgrading to 2.9.9.2 causes the application to crash with aforementioned error.

[philsttr]

This was caused by FasterXML/jackson-databind#2395

Use jackson 2.9.9.3 or above to fix it.
