----------------------------

    Resolution: Done


You know get a warning like the following instead:

WARN  [ClassLoadingSpace] MockClassLoaderPolicyModule b:1.0.0 resolved ModuleRequirement{a [1.0.0,2.0.0)} to MockClassLoaderPolicyModul
e a:1.0.0 which has import-all=true. Cannot check its consistency.

>
> If a classloading module has import-all=true we can't do a consistency check because its imports are not known.
> This means the module has no classloading space.
> Currently this leads to an NPE when such a module is resolved as an import of another module that is not imort-all=true
> and it then tries to join with the non-existent space.
> java.lang.NullPointerException
> 	at org.jboss.classloading.spi.dependency.ClassLoadingSpace.resolve(ClassLoadingSpace.java:325)
> 	at org.jboss.classloading.spi.dependency.ClassLoadingSpace.joinAndResolve(ClassLoadingSpace.java:122)
> The joining should not happen if the resolved module doesn't belong to a classloading space,
> i.e. import-all=true
