Description

Starting Operation Intelligence context is failing with:

Failed to start pipeline, java.lang.NoClassDefFoundError: Could not initialize class org.apache.ignite.internal.util.IgniteUtils

This is because the Ignite version we are currently using v2.5.3 does not support Java11.

1. Install the MID server following the documentation MID Server for Operational Intelligence.
2. Make sure that JRE11 is the one installed on this host and used by the mid server. You can check by following our documentation Install a MID Server on Windows under section "Configure a MID Server on Windows to use an existing JRE. 
3. Setup the Operational Intelligence context by following our documentationConfigure the Operational Intelligence extension
