I am currently trying to develop an api that utilizes apache ignite as an in memory cache. In the IDE I am able to get everything running and the ignite cache starts up with no issues. When I try to deploy the war file onto tomcat it seems like there is an issue trying to start up ignite. From what I have seen it looks to be possible but I cant seem to find any configuration settings whether it be in Tomcat or ignite that will allow me to do so.
The following is my pom.xml dependencies
<properties>
<java.version>17</java.version>
<ignite.version>2.14.0</ignite.version>
<h2.version>1.4.197</h2.version>
</properties>
<dependencies>

For testing purposes I just start up ignite with
Ignition.start()
upon requesting an api endpoint to start up the ignite node i see the following error logs in Tomcat

The reason is your Tomcat seems to be running under Java 17. All the deployed apps reside in the same JVM, so you need to run it with proper startup options (with --add-opens). Please refer to the docs.
This behaviour was introduced as a part of the Jigsaw project - JSR 376.
This question sheds some light as well.
