HiveMind issue
The HM support list was not helpful on this, so I hope you don't mind me
asking this.
I have an application using HiveMind, where the registry construction fails.
The strange thing is that HM classes in the JAR are accessible, but HM
cannot find a service point in its own hivemodule, i.e. hivemodule.Startup?

That may be a classloader issue. I wonder if Maven2 uses some weird
classloader which doesn't find the resources (the /META-INF/hivemodule.xml
files).

like this Norbi:

VTMain main = (VTMain) registry.getService(VTMain.class);

No, not yet. I thought the stack trace would be enough. I can get it to run
directly in JBuilder, or Eclipse but not from a Maven2 build.

How is the registry created?
Did you debugged why and where is that NPE thrown?
