Launch your websphere server to space with spring boot.

This project demonstrates the possibility of launching spring boot data jpa hibernate apps in WAS 8.5.5.9 (lower versions aren't possible)

Main magic happens in HikariCPConfig && HibernatePersistenceProviderResolver. Basically it uses tips from http://stackoverflow.com/a/34487223

In some cases you'll also need to set your classloader setting to parent last.
