Description

When using the GenerateTableFetch, I found myself into the following situation: using the processor as a source processor (no incoming connection) but setting the failure relationship back on the processor itself. With this setup the processor will never do anything and will not generate any kind of log message.

I know it didn't make sense to use the failure relationship on a source processor and that the behavior is described in the documentation, but it could be useful to add a warning in such a situation (for people like me ).
