java.lang.IllegalStateException: There's already another KieContainer created from a different ClassLoader

I deployed 2 war files in wildfly 14. Both of them are drools projects that are trying to execute some rules. The problem is that only one of the war file is able to execute drools rule. The other fails with the below Internal Server Error:
