----------------------------------------
Summary: problem parsing RabbitMQ events
Key: CLOUDSTACK-8680
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8680
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Affects Versions: 4.5.1
Reporter: Yiping Zhang
RabbitMQ event message for VM.CREATE and VM.DESTROY events can't be parsed
cleanly. Here is an example:
{

}
There are two problems for above example:
1. The nested data structures are not parsed properly. As you can see, values
for both “cmdInfo” and “jobResult” are strings instead of nested hash. I have
to make additional calls to JSON parser on those values to parse them.
2. The string
"org.apache.cloudstack.api.response.UserVmResponse/virtualmachine/“ at the
beginning of the value for “jobResult” makes this value invalid to be parsed as
JSON object at all.
