    Module getClassLoader().getResource doesn't find folder name but folder content

    lehnerj Newbie

      Dear JBoss Community,

       

      we upgraded from JBoss 7.1.1.Final to EAP 6.1.0 Final and encountered the following problem:

       

      We want to read some stub data from <JBOSS_HOME>/modules/de/example/main/folder/ but getClassLoader().getResource("folder") returns null, this worked in JBoss 7.1.1.Final and in JBoss EAP 6.1.0.Beta1.

       

      Can you please help us, solving this problem?

       

      Environment: Windows 7, Java JDK 7_21, 64 Bit

       

      Prior to EAP 6.1.0 Final an ..index file was automatically created in <jboss_home>/modules/de/example/main, this file is now missing.

      If I add it manually it doesn't help either.

       

      Please see the maven project attached to reproduce the problem.

       

      Output JBoss 7.1.1.Final & EAP 6.1.0.Beta1:

      ERROR [stderr 71] (MSC service thread 1-15) file: /D:/std/tools/jboss-as-7.1.1.Final/modules/de/example/main/./example.properties
