Stacktrace after hardware refresh #11287
Description
I deployed new code and after the hardware refresh, I wasn't able to view that server anymore as json parsing was failing, and the following exception was thrown.
Looking bit further, I came to know that hibernate was failing when mapping this part https://github.com/uyuni-project/uyuni/blob/master/java/core/src/main/java/com/redhat/rhn/domain/server/CPU.java#L102
I didn't get the chance to fix it but this is a real bug which needs fixing.
In my case, sample json for this database column was the following
{"family": "ARM", "signature": "Implementor 0x61, Variant 0x0, Architecture 15, Part 0x000, Revision 0", "manufacturer": "Apple"}
Caused by: java.lang.NullPointerException
