[jboss-dev-forums] [Design the new POJO MicroContainer] - NPE in CLSpace
DML found this NPE in CLSpace:

Take this three config files
| <classloading name="jboss-threads-classloader"
version="1.0.0.Alpha" xmlns="urn:jboss:classloading:1.0">
| <capabilities>
| <module name="jboss-threads"
version="1.0.0.Alpha"/>
| <package name="org.jboss.threads"
version="1.0.0.Alpha"/>
| </capabilities>
| <requirements/>
| </classloading>
|
| <classloading name="jboss-threads-deployer-classloader"
version="1.0.0.Alpha" xmlns="urn:jboss:classloading:1.0">
| <requirements>
| <module name="jboss-threads"/>
| <package name="org.jboss.deployers.vfs.deployer.kernel"/>
| <package name="org.jboss.deployers.vfs.spi.deployer"/>
| </requirements>
| </classloading>
|
| <classloading name="jboss-kernel-classloader"
version="2.0.0.GA" xmlns="urn:jboss:classloading:1.0"
import-all="true">
| <capabilities>
| <package name="org.jboss.deployers.vfs.deployer.kernel"/>
| <package name="org.jboss.deployers.vfs.spi.deployer"/>
| </capabilities>
| <requirements/>
| </classloading>
|
And you end up with
| JBoss-MC-Demo ERROR [04-12-2008 23:56:08] AbstractKernelController - Error resolving
dependencies for ClassLoader: name=vfsfile:/C:/projects/demos/sandbox/deployers/

The cause is the CLMD/module with import-all="true" and this code in
Domain::addModule
| // Skip the classloader space checking when it is import all
| if (module.isImportAll() == false)
| {
| ClassLoadingSpace space = new ClassLoadingSpace();
| space.join(module);
| }
|
Module never joins any CLSpace.
