---------------------------------
Summary: Ensure JDBC Driver is deregistered when it gets loaded in
the HikariCPConnectionPool
Key: NIFI-15383
URL: https://issues.apache.org/jira/browse/NIFI-15383
Project: Apache NiFi
Issue Type: Bug
Reporter: Bob Paulin
When the HikariCPConnectionPool loads a Driver it registeres to the
DriverManager on class load with many current drivers. The DriverManager
exists in the System Classloader. This will prevent the InstanceClassLoader
that the HikariCPConnectionPool is running in from being Garbage Collected.
The Driver should be deregistered onRemove to prevent this leak.
