Devdeep Singh commented on CLOUDSTACK-7136:
-------------------------------------------
The issue seems to be related to custom disk offering. For a custom disk
offering the cpu and memory values are null and the user specifies them while
creating an instance. In the allocator, these values are expected to be present
in the offering object. This causes a null pointer exception.
