Fix error prone BoxedPrimitiveEquality report

Change 517822 [1] caused error prone to be run also for the healthcheck
plugin. Truthfully, I looked into the commit as much as I could but
didn't come up with a clear explanation as to why that is.

Address the error prone issue to enable compiling the plugin again.
