I have to compile and run a seam-2.2.2 app in java 8 environment. Everything works fine, except seam identity management. This seems to be relate to Drools from seam-2.2.2
when I run the seam app in java 8 environment, this following exception is raised org.jboss.seam.InstantiationException: Could not instantiate Seam component: org.jboss.seam.security.ruleBasedPermissionResolver
Excluding drools form the app, no more exception. The seam app is working correctly.
The exception is not raised in java 5 environment.
