> The VM is not stopped, and the API returns the following error:
> {noformat}
> HTTP/1.1 530 : InvocationTargetException when invoking event handler for subject: job.eventpublish
> {noformat}
> The error comes from JSON parsing in https://github.com/apache/cloudstack/blob/339355594ca537ebbc8e0a0f6e49a63ee4b884ac/server/src/com/cloud/api/ApiServer.java#L270
> The {{substring}} method throws a StringIndexOutOfBoundsException when {{cmdEventType}}
is the last field in the JSON object.
> The JSON object being the JSON serialization of a {{HashMap}} object, the order of the
fields is not guaranteed. In my tests, I observed that there is no error with Java 7, but
it fails with Java 8, which has a different Hashmap implementation.
> For example, with request {{http://127.0.0.1:8096/client/api?command=stopVirtualMachine&id=734ef752-fe99-4d46-8f31-18130496473c}},
cmdInfo is:
> {noformat}
> {"ctxUserId":"1","httpmethod":"GET","ctxStartEventId":"105","id":"734ef752-fe99-4d46-8f31-18130496473c","ctxDetails":"{\"interface
com.cloud.vm.VirtualMachine\":\"734ef752-fe99-4d46-8f31-18130496473c\"}","ctxAccountId":"1","uuid":"734ef752-fe99-4d46-8f31-18130496473c","cmdEventType":"VM.STOP"}
> {noformat}
> and it fails.
> Please note that the error is not present for all API requests, depending on the parameters
fields.
