[undertow-dev] Fwd: Issue with Java 9 (Jigsaw) when using Undertow

Hi, I'm using the Spring Boot starter for Undertow. The dependencies which are pulled in are: org.springframework.boot:spring-boot-starter-undertow:jar:2.0.0.M3:compile | +- io.undertow:undertow-core:jar:1.4.18.Final:compile | | +- org.jboss.xnio:xnio-api:jar:3.3.8.Final:compile | | \- org.jboss.xnio:xnio-nio:jar:3.3.8.Final:runtime | +- io.undertow:undertow-servlet:jar:1.4.18.Final:compile | | \- org.jboss.spec.javax.annotation:jboss-annotations- api_1.2_spec:jar:1.0.0.Final:compile | +- io.undertow:undertow-websockets-jsr:jar:1.4.18.Final:compile | | \- org.jboss.spec.javax.websocket:jboss-websocket-api_ 1.1_spec:jar:1.1.0.Final:compile | +- javax.servlet:javax.servlet-api:jar:3.1.0:compile | \- org.glassfish:javax.el:jar:3.0.0:compile Now, when I run the application through Java 9 (Release candidate) and I have a module-info.java (Jigsaw), then I get the following error: Error occurred during initialization of boot layer java.lang.module.FindException: Unable to derive module descriptor for C:\Users\xxxxx\.m2\repository\org\jboss\spec\javax\ annotation\jboss-annotations-api_1.2_spec\1.0.0.Final\ jboss-annotations-api_1.2_spec-1.0.0.Final.jar Caused by: java.lang.IllegalArgumentException: jboss.annotations.api.1.2.spec: Invalid module name: '1' is not a Java identifier It seems there is an issue with the determination of the naming of the automatic module. I expect to have the same issue for jboss-websocket-api_1.1_spec. The name of the jar file isn't aligned on the algorithm defined under ( http://download.java.net/java/jigsaw/docs/api/java/ lang/module/ModuleFinder.html). Is anyone aware of this issue? Is this something that can be resolved?
