If you were attempting to accomplish a task, what was it you were attempting to do? Trying to push an app that has version 0.5.2 of the mysql2 gem as the DB adapter.

You get the following error:

Hi @crstamps2 - Can we get a sample app to reproduce the issue? I tried reproducing the issue (our ruby_2.2_bundler_2 fixture uses mysql2 0.5.2), and successfully built the app with no issues.

[tylerphelan]

@crstamps2 closing this one out since we can't reproduce and we have a passing test that is using this gem. If you're seeing issues with PAS, opening a Pivotal support ticket is a way to get quicker responses.
