Servoy 2019.09 notation warnings

Since I have upgraded to Servoy 2019.09, I get notation warnings about:

@type {webnotificationsToastr.toastrOptions}
@type {Array<servoyextra-sidenav.MenuItem>}
@type {Array<bootstrapextracomponents-navbar.menuItem>}

I couldn’t detect any functional limitations, but the warnings are confusing me.
