We saw illegal reflective access warnings using Wildfly and Java 9/10 for different classes during the last couple of months. We know this is related to Java's module system. The most recent occurrence is with Wildfly 14 and Java 10:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.jboss.as.server.deployment.reflect.ClassReflectionIndex (jar:file:/Users/.../wildfly-14.0.0.Final/modules/system/layers/base/org/jboss/as/server/main/wildfly-server-6.0.1.Final.jar!/) to method java.lang.Object.finalize()
WARNING: Please consider reporting this to the maintainers of org.jboss.as.server.deployment.reflect.ClassReflectionIndex
Should we file a bug, or is it reasonable to assume that you guys will notice such warnings anyway and fix them?
file a bug please
