NullPointerException during 
registerModelObject(AbstractCompositeContext.java:446) 
-----------------------------------------------------------------------------------

                 Key: TUSCANY-586
                 URL: http://issues.apache.org/jira/browse/TUSCANY-586
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Core
    Affects Versions: Java-M1
         Environment: Windows XP
            Reporter: Yang Lei


The scenario is:

My sca.module file is in different location than the classpath location, so I 
use binaryClassLoader to indicate where to load binaries, use muduleURI to 
indicate the sca.module location.

The code causing problem is like the following: 

                             ResourceLoader resourceLoader = new 
ResourceLoaderImpl(binaryClassLoader);
...
                AssemblyContext modelContext = new 
AssemblyContextImpl(modelFactory, modelLoader, resourceLoader);
                ModuleComponentConfigurationLoader loader = 
BootstrapHelper.getConfigurationLoader(systemContext, modelContext);
                ModuleComponent moduleComponent = 
loader.loadModuleComponent(name,configURI, new URL(moduleURI));
                rootContext.registerModelObject(moduleComponent);

The exception is: 

Stack Dump = java.lang.NullPointerException

Appreciate the fix.
