Is the warning 'Error while registration of Discovery instance' really necessary? #395

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I am using xdocreport-1.0.4.jar, velocity-1.7.jar and referring explicitly to 
Velocity:

IXDocReport report = XDocReportRegistry.getRegistry().loadReport( in, 
TemplateEngineKind.Velocity );

Still I get a warning which I think is not necessary to log:

xdocreport-1.0.4.jar merge the whole feature of XDocReport. The stack strace is 
about Freemarker template engine initialisation (and in your case, Freemarker 
is not in your classpath).

To avoid this problem, you should use each JARs you need (core, template, 
freemarker, etc).
