java.sql.SQLTransientConnectionException: spring HikariCP - Connection is not available, request timed out afte

I've catched java.sql.SQLTransientConnectionException: springHikariCP - Connection is not available, request timed out after 30001ms.

First code block works well, second (CP) does not work.

What is wrong and how fix this?

JDK - 1.8.0_73.

HikariCP - 2.4.5.

Spring - 4.2.5.RELEASE.
