Our environment is as follow:

Apache Tomcat 7.0.72

Version 1.5.5 and 1.4.6 does not have this issue.
We are able to trigger this when using JDBI to return generated keys:

.....
Tracing through, it appears that the generated keys are returned successfully, no exceptions are thrown, but packetFetcher is indeed null in:
I can also confirm that this issue does not appear in 1.5.5
The particular datatype of the incremented key is a BIGINT(20) in case that makes a difference. Once the row is inserted, SELECTing the row works as expected even in 1.5.6.
