Expected Behavior

When asking the user if java sources reconciling should be activated, maybe give a little hint or link to documentation, what it's supposed to do.
Current Behavior

just ask if to enable it or not. Afterwards I was unable to find the setting to deactivate it again.

Context
I've updated Eclipse and the Spring Tools Extension when I was asked if I want to enable "additional Spring java sources reconciling". Without any further explanation. Couldn-t find anything on google about it. But found out that the question was probably its from the Spring Tool extension (if not, close that issue). Tried to find the setting, to enable/disable it to see what difference it makes. But also can't find that setting anywhere.
