ClassNotFound exception when connecting a remote HornetQ client over SSL ------------------------------------------------------------------------ Key: WFLY-4259 URL: https://issues.jboss.org/browse/WFLY-4259 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 8.1.0.Final, 8.2.0.Final Reporter: Jon Kranes Assignee: Jeff Mesnil When using HornetQ with a remote client connecting with SSL (using a netty-connector with ssl-enabled=true) the server throws an exception in ModuleClassLoader when the client attempts to connect. The exception is: java.lang.ClassNotFoundException: javax.net.SSLException After doing some investigation I was able to resolve this issue by adding a dependency in the io.netty module.xml file <dependencies> <module name="javax.api"/> <dependencies Without this dependency, it appear that Netty is unable to load classes that it needs from javax.net.ssl. NOTE: adding this dependency resolves the issue in Wildfly 8.2.0.Final. However, it does NOT resolve the issue in 8.1.0.Final. Even after adding this dependency I still got the ClassNotFoundException.
