Is this a bug?

Hi,
I have some startup issues with the Workshop Plugin.
I get the following Exception:

Loading plugins from packages.
>>> All dependencies have been resolved

...

 I have not figured out how to reproduce the error...

I found out that the Exception was triggered by a errornous @PluginVariant(...) definition.

The line was:

@PluginVariant(variantLabel = "Test", requiredParameterLabels = { 0, 1 } )
public static Petrinet test(PluginContext context, XLog log) {}

The requiredParameterLabels = { ... } had too many entries...

Corrected @PluginVariant:

@PluginVariant(variantLabel = "Test", requiredParameterLabels = { 0 } )
public static Petrinet test(PluginContext context, XLog log) { }
