NPE in Hibernate when Connection accessed from thread that did not create it

[brettwooldridge]

Hi,

Just bumped up to the latest version (from 1.2.1) and now I'm getting this error, which is causing the transaction to rollback. This was okay on 1.2.1 (no code changes, just a version bump).

Today HikariCP 1.2.6 was published to the maven repository containing this fix.
