Rohit Yadav commented on CLOUDSTACK-1070:
-----------------------------------------
Kelven, I fixed CLOUDSTACK-1237 and found that adding the component in xml is
not the right fix. It was already having the @Component annotation.
The problem was no adapter was returned as getName() was not implemented by the
implementing adapter which should return one of the static class's attributes.
I found that it was sort of a regression due to the baremetal merge.
