Including plugin breaks the redshift driver

[alvaroc1]

When I include it like this:

resolvers += Resolver.bintrayIvyRepo("kamon-io", "sbt-plugins")
addSbtPlugin("io.kamon" % "sbt-aspectj-runner-play-2.6" % "1.1.0")

I get an error on startup when play tries to start up a connection to redshift using these settings:

db {
  ...
  reporting {
    driver = "com.amazon.redshift.jdbc42.Driver"
    url = "jdbc:redshift://....redshift.amazonaws.com:5439/dbname"
    username = "..."
    password = "..."
  }
}

Driver jar: https://s3.amazonaws.com/redshift-downloads/drivers/jdbc/1.2.12.1017/RedshiftJDBC42-1.2.12.1017.jar

The error disappears if I remove the sbt plugin.
