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

[Galder Zamarreño]

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?
