> 4.2 KVM agent sends wrong StartupRoutingCommand to 4.1 management server
> ------------------------------------------------------------------------
>
> Key: CLOUDSTACK-3714
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3714
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM
> Affects Versions: 4.2.0
> Environment: 4.2 agent with 4.1 management server
> Reporter: Wido den Hollander
>
> When the Agent starts it sends a StartupRoutingCommand to the management
> server, but this has changed it seems:
> In 4.1 the Agent sends this JSON:
> Sending Startup: Seq 4-0: { Cmd , MgmtId: -1, via: 4, Ver: v1, Flags: 1,
> [{"StartupRoutingCommand":{
> In 4.2 however the JSON data starts with:
> Sending Startup: Seq 1-6: { Cmd , MgmtId: -1, via: 1, Ver: v1, Flags: 1,
> [{"com.cloud.agent.api.StartupRoutingCommand":{
> So the Agent sends the full name of the class and this confuses the
> Management server, it throws an Exception:
> Caused by: com.cloud.utils.exception.CloudRuntimeException: can't find
> com.cloud.agent.api.com.cloud.agent.api.StartupRoutingCommand
> at
> com.cloud.agent.transport.ArrayTypeAdaptor.deserialize(ArrayTypeAdaptor.java:79)
> at
> com.cloud.agent.transport.ArrayTypeAdaptor.deserialize(ArrayTypeAdaptor.java:37)
> at
> com.google.gson.JsonDeserializerExceptionWrapper.deserialize(JsonDeserializerExceptionWrapper.java:51)
> ... 15 more
> So it's searching for
> "com.cloud.agent.api.com.cloud.agent.api.StartupRoutingCommand" which
> obviously fails.
