Compiler errors when upgrading from 3.0.8 to 3.3.2

Summary: In an attempt to upgrade the JDBC driver that JetBrains uses for DataGrip, I simply changed the dependency from 3.0.8 to 3.3.2. It builds successfully with 3.0.8 but fails with 3.3.2.

Repro:

1. Fork driver here: https://github.com/DataGrip/couchbase-jdbc-driver
2. Run build script (for Windows it's `.\gradlew.bat jar`)
3. Build succeeds.
4. Update build.gradle line 31 to use 3.3.2
5. Run build script

Expected:

Build success.

Actual:

Build fails with 7 errors / 1 warning.

Notes:

I've attached the failed build output.
