Not sure that I follow the exact format you intend. I now have
String message = "method " + methodName + " of " + this.toString() + "
in module [" + module.name() + "] of layer [" + module.layer().name()
+ "]";
which gives me something like
Caused by: java.lang.NullPointerException
at method get of NativeRepositoryService:NativeRepositoryService in
module [RdfIndexing Module] of layer [Infrastructure Layer].(:0)
the this.toString() is the CompositeModel.toString(), which for
ServiceComposites are primaryType:idenity but only primaryType for other
composite meta types.
I am not sure a concise format without telling what each part is, is
particularly friendly for adoption. In the above, I realize that should
probably have quotes around "get", since it otherwise risk to be to obscure.
