Problem Description

When deploying an EAR with more than one WAR inside many ClassNotFoundExceptions are logged. Depending on the application there can be thouthands of warnings. For example if you use bootsfaces, one of them looks like that:

[2022-04-29T12:44:11.265+0000] [glassfish 5.1] [WARNING] [AS-WEB-UTIL-00035] [javax.enterprise.web.util] [tid: _ThreadID=96 _ThreadName=admin-listener(2)] [timeMillis: 1651236251265] [levelValue: 900] [[
  Unable to load class net.bootsfaces.component.icon.Icon, reason: java.lang.ClassNotFoundException: net.bootsfaces.component.icon.Icon]]

This seems to be a known problem and was fixed for Payara: https://github.com/payara/Payara/issues/374 Is it possible to fix this problem in Glassfish in the same way?
