Description

We're getting errors in OpenFE during minimization of the multistate sampler. This appears to be because a handler for NaN in the FIRE minimizer was not updated to match OpenMM's changed error message. (I note that other lines seem to have updated). See OpenFreeEnergy/openfe#253 (comment) and following.

Nice catch! This might actually solve some of the stability issues some users been seeing when minimizing. Thanks!

Would this one solve #686 ?

No; that was caught as a follow-up to this (we were seeing 100% failures at minimization). There's a more fundamental issue in the FIRE minimization.
