[ https://issues.jboss.org/browse/WFCORE-3205?page=com.atlassian.jira.plugi... ] James Perkins commented on WFCORE-3205: --------------------------------------- It looks like the jboss-logmanager in the cases of a standalone application may be getting loaded twice. Since the {{org.wildfly.core:wildfly-embedded}} has a dependency on {{org.jboss.logmanager:jboss-logmanager}} using Maven or another build tool may bring in the log manager dependency. This will get loaded on the JVM's default class loader, then the modular class loader will load the library again. Excluding the dependency on the log manager seems to resolve the issue. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
