Why does Flexy-Pool cause a NoSuchElementException when configured via Spring in Apache Storm

QUESTION

Why does Flexy-Pool cause a NoSuchElementException when configured via Spring in Apache Storm

Asked 2018-Feb-07 at 10:36

I have an Apache Storm (1.1.1) based application, which uses Spring (5.0.3) to configure and inject Hibernate-based (5.2.12) database services, which connect to a PostgreSQL database.

Between Hibernate and the database, I have configured flexy-pool (2.0.0) on top of HikariCP (2.7.6) as a datasource (see Figure A). The application is launched on some Ubuntu 16.04 LTS server instances with the latest OpenJDK 8 version.

I experience sad runtime exceptions related to flexy-pool after starting my Storm topology. However, this is not deterministic. Sometimes it will work, sometimes the exception below will be thrown. If I do not use flexy-pool in my application (see Figure B) everything works everytime as expected.
