Request to update jackson-databind library to the latest 2.9.x

Expected Behavior

I am trying to build a plugin which requires 2.9.x version of jackson-databind. The plugin tests works independently. But when I install it into graylog 3.x, it fails with the follwing error message:

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Scala module 2.9.6 requires Jackson Databind version >= 2.9.0 and < 2.10.0
graylog_1        | 	at com.fasterxml.jackson.module.scala.JacksonModule$class.setupModule(JacksonModule.scala:61)
graylog_1        | 	at com.fasterxml.jackson.module.scala.DefaultScalaModule.setupModule(DefaultScalaModule.scala:18)

Possible Solution

Upgrade jackson-databind to 2.9.x

Context

The plugin I am building depends on jackson-databind 2.9.x version transitively. But graylog still uses the older version of it: 2.8.11.3. This version mismatch causing a runtime error when the plugin is being loaded.

Your Environment

• Graylog Version: 3.0.0
• Elasticsearch Version: 6.5.1
• MongoDB Version: 3.x
• Operating System: Centos
• Browser version: Chrome/Safari

I vaguely remember that there were issues with the update, but I can't recall the details anymore.
At the moment I can't promise a target date for updating this dependency.

Can you maybe shade your dependency in the plugin to allow making progress?

I tried using the 2.9.x in the plugin. But when installed into Graylog, somehow the class loaders choosing the class from older libraries. I think there are some setting to choose a dedicated class loader for plugin. Should I try go in that direction?

We updated to Jackson 2.9.10 in the meantime.
