API REST - Exception when importing a unexistent Test Execution result with a non-existent issue test

If we call jira/rest/raven/1.0/import/execution/ with a new test execution. If the tests inside doesn't exist then, we get an exception.

If the test executions exists, there is no problem and we get a warning telling that the test execution doesn't contain or is not associate with this non existent test.

Example:

{
"info" :

{ "summary" : "Execution of automated tests for release v1.3", "description" : "This execution is automatically created when importing execution results from an external source", "version" : "", "user" : "admin", "revision" : "1.0.42134", "startDate" : "2014-08-30T11:47:35+01:00", "finishDate" : "2014-08-30T11:53:00+01:00" }

,
"tests" : [

{ "testKey" : "NON-EXISTENT-ISSUE", "start" : "2014-08-30T11:47:35+01:00", "finish" : "2014-08-30T11:50:56+01:00", "comment" : "Successful execution", "status" : "PASS" }

]
}

NOTE: this only happens when there is no "tests" with a valid "testKey" in the list.
