copied!<p>Since you're asking about the thinking of the people behind WildFly, I will refer you to the following mail-list message. It was posted to the Jigsaw development list by David Lloyd, who is (I believe) the designer of JBoss Modules on which WildFly is based. The context was a discussion about the introduction of a service model into Jigsaw: <a href="http://mail.openjdk.java.net/pipermail/jigsaw-dev/2012-February/002161.html">http://mail.openjdk.java.net/pipermail/jigsaw-dev/2012-February/002161.html</a></p> <p>What David seems to be saying is either that the <em>idea</em> of services itself flawed – i.e. you don't need them! – or that the requirement is already sufficiently solved by the ServiceLoader API which was introduced in Java 6.</p> <p>However, ServiceLoader is known not to work on module systems that use classloader isolation, which includes both OSGi and JBoss Modules. This is because ServiceLoader uses classpath scanning, and in a module system there is no "classpath". In OSGi we have specced a way of adapting ServiceLoader (though it's yucky and requires bytecode munging). Perhaps JBoss Modules also has a way of handling this, but I couldn't find anything from a quick scan of their docs.</p> <p>Anyway as I said in my comment above, I'm puzzled about your motivation. You clearly get benefits from the service model provided by OSGi, and JBoss-OSGi is still available and supported by Red Hat... so why not continue to use it? Especially if there is nothing clearly provided by WildFly out-of-the-box that does what you want.</p>
