I have a production application using Spring JPA + Hibernate + MySQL.

On Feb 13th, with no code or library changes it started saving java.time.LocalDate as 1 day less.

For example LocalDate.of(2017, 3, 12) or older saves to MySQL correctly.
However, LocalDate.of(2017, 3, 13) saves to MySQL as 2017-03-12,
and LocalDate.of(2017, 3, 14) saves to MySQL as 2017-03-13, etc...

I created a test application to verify and demonstrate.
It test saves a LocalDate and a unique integer (month * 100 + day) for each day in March.
Up to the 12th works correctly, afterwards it saves each day as 1 day less.

Here is a dump of the MySQL table after the test completes:
