jdbc: fix testing on Tarantool 2.1 #90
Description
https://travis-ci.org/tarantool/tarantool-java/jobs/455319926#L1724
Tarantool 2.1 now supports strict types. List of supported types is on the wiki. We need to update our tests accordingly.
The change on tarantool side can broke some jdbc testing scenarious (e. g. date/time is broken until #3694). If so we need to file issues here and mark them as blocked by related tarantool issues.
