Fixes #249 ☕️

@skuruppu
The build error for the code format seems to be caused by a non-related problem. The failing integration test that is fixed by this PR is however breaking all other PRs, so I think we should consider merging this PR even without a successful Code Format check.

Oooh I have no idea what this error means:

java.lang.UnsupportedClassVersionError: com/google/googlejavaformat/java/FormatterException has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Unfortunately, I don't have the permissions to force-merge PRs.

This will be fixed by google-cloud-shared-config 0.7.0 which is releasing now.

@stephaniewang526 are these extra auto value changes expected from shared-config 0.7.0?

[olavloite]

@chingor13 Any idea why it seems like Java11 needs to be used for the Code Format build for it to succeed? Or am I missing something there?

So the lint error after updating the shared config was because we also need to update .kokoro/build.sh from https://github.com/googleapis/java-spanner/pull/251/files#diff-ce0d2ea7b6085e6c4bd286d0a15a3971

The auto value changes don't seem to be necessary unless you use auto value

Great, thanks for looking into that. I'll include that change here and try to walk back as many of the other changes as possible while still keeping the build green. Once that's done, I'll try to fix the other PR's that are failing because of the integration test that is fixed by this PR.

[stephaniewang526]

@olavloite is the autovalue change in shared-config affecting you somehow?

[skuruppu]

I'm going to merge this in while the build is green. Then I'll get the presubmits running on the other PRs that are blocked.
