问题
I have a drools implementation using Drools 7.12.0.Final that works perfectly under WildFly-10.1.0.FINAL. We are now trying to upgrade to WildFly-19.0.0.FINAL and the drools module will not load. I see this in the logs as Wildfly tries to start the Drools module;

I know going from 10.0.1 to 19.0.0 is a big jump but I have no choice in the matter. Can anyone point me to what is wrong. I've seen some StackOverflow posts that suggest that the xmlns should be changed to
kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule"
but that has made no difference. Any help would be appreciated.
回答1:
The error was happening in ClasspathKieProject when Drools was trying to use org.jboss.vfs.VirtualFile to read the kmodule.xml. This is caused by changes to the JBoss Virtual File System that WildFly uses (details of the fix are at https://github.com/kiegroup/drools/commit/2a36f67a29ed06d0f980a60ff1c81fa897e8147a)
However, upgrading to the latest Drools (7.37.0.Final at this time) fixes the problem.
