> Repro steps:
> This bug is not reproducible through CloudStack UI. Steps to reproduce this bug:
> 1. Deploy a VM without passing any parameters in Name and Description (last step in deploy VM wizard).
> 2. Stop this VM.
> 3. Fire updateVIrtualMachine API without passing "displayName" parameter, you'll see NPE in MS logs. Do not try  with UI because UI will pass displayName paramter with blank value.
> Bug:
> Hitting java NPE as soon as calling update virtual machine api
