Thanks for the fix.
The original motivation for adding it was the following:
Users requested a way to have one central configuration file for all their
job's UDFs. With setting global job parameters (for example the ParameterTool),
they can use a properties file and the KVs from there are accessible from all
UDFs.
Also, the same user wanted to have these configuration properties
accessible in the webinterface. So if the `toMap()` method is overwritten (the
ParameterTool is doing that), the job parameters are accessible from the web
interface.
