limit queries of single finders to 2

[tschniewind]

Enhancement:
Given a repositorys find-method returning a single result or an java.util.Optional should limit the underlying query to 2.

This would help to get the expected Result in case of multiple rows (IncorrectResultSizeDataAccessException) even if the query leads to huge result set.

(We had a case leading to an out of memory exception cause the query found about 50000 rows. Unfortunately we could not use a UniqueConstraint.)

In which version will this enhancement be integrated, any idea?

This will be part of the next 3.0 milestone and therefore eventually in 3.0 GA.
