title: Disabling hibernate validation annotations dynamically at runtime?
body: <p>Is it possible to turn off certain constraints / annotations per class at runtime?  For instance if I wanted to turn of a <code>@NotNull</code> check on a <code>firstName</code> field, is that possible?</p>
  
  <p>This would make testing to see whether a certain constraint is triggered correctly simpler, as I could turn off all the other constraints, and just check that one constraint.</p>
