Projection data is not mapped correctly on Hibernate 5.0

Incorrectly mapped values on page summaries.

See https://github.com/spring-projects/spring-boot/issues/12720 for a test that reproduces the error.

The problem seems to come from this line in the test

Page<HotelSummary> hotels = this.repository.findByCity(city,
		new PageRequest(0, 10, Direction.ASC, "name"));

For some reason the HotelSummary seems to have data mapped to the wrong methods. Digging in a bit, the problem appears to be somewhere in org.springframework.data.repository.query.ResultProcessor. Specifically getProjectionTarget is called with a source containing the following:

[Atlanta,GA,USA, Doubletree, 2.0]

And attempts to convert it using toMap. This gets passed the following names:

[averageRating, city, name]

There are not in the same order. Perhaps DefaultProjectionInformation.collectDescriptors is not returning methods in a defined order. Possibly related to SPR-16675?
