java – Eclipse showing ‘Object’ instead of correct type for var

I am new to the var keyword, and I am trying to understand something in Eclipse.

The code I have is:

Map<Integer, Set<Integer>> savedConfirmations = USERS.fetchStaffAccessConfirmed(managerId, dates)
    .collect(Collectors.toMap(Entry::getKey, (o) -> o.getValue().keySet()));

When I change the type from Map<Integer, Set<Integer>> to var Eclipse tells me it is an Object when I hover over it.

Correct type

Incorrect type

However I am able to use the variable as if it is a Map<Integer, Set<Integer>> in both ways without error.



It appears to only effect Collectors.toMap, as if I collect to a List the hover shows its correct type.

Is there something I am misunderstanding about var?
