[jboss-as7-dev] Module jars dissapearing leaving empty classes/ folders and errors

Hi all, We’re having issues with our Infinispan Server integration tests, which run within Wildfly 8.0.0.Beta1 (as I’m typing I’m wondering if we should just upgrade it to see if this goes away...?). Quite often some of the runs fail with error message [1]. Having looked at the build environment when a run fails, you see this: -- $ ls modules/system/layers/base/org/infinispan/server/rest/main drwxrwxr-x 2 g staff 68B Feb 3 18:41 classes (<— a directory??) -rw-r--r-- 1 g staff 1B Feb 3 18:41 classes.index -rw-r--r-- 1 g staff 2.1K Feb 3 18:41 module.xml $ ls modules/system/layers/base/org/infinispan/server/rest/main/classes drwxrwxr-x 2 g staff 68B Feb 3 18:41 . drwxrwxr-x 5 g staff 170B Feb 3 18:41 .. $ more modules/system/layers/base/org/infinispan/server/rest/main/module.xml <module xmlns="urn:jboss:module:1.1" name="org.infinispan.server.rest”> ... <resource-root path="classes"/> ... This is completely different to what happens with a successful run: -- $ ls modules/system/layers/base/org/infinispan/server/rest/main -rw-r--r-- 1 g staff 103K Feb 3 19:40 infinispan-classes.jar (<— a jar file!) -rw-r--r-- 1 g staff 278B Feb 3 19:40 infinispan-classes.jar.index -rw-r--r-- 1 g staff 2.1K Feb 3 19:40 module.xml $ jar tf modules/system/layers/base/org/infinispan/server/rest/main/infinispan-classes.jar | grep ExtendedHeaders org/infinispan/rest/configuration/ExtendedHeaders.class $ more modules/system/layers/base/org/infinispan/server/rest/main/module.xml <module xmlns="urn:jboss:module:1.1" name="org.infinispan.server.rest”> ... <resource-root path="infinispan-classes.jar”/> — Anyone can explain what is going on here? Does it ring a bell to anyone? Is this a known Wildfly issue by any chance?
