-------------------------------------
Resolution: Fixed
> camel-grpc: Port validation should check if a port was specified
> ----------------------------------------------------------------
>
> Key: CAMEL-20534
> URL: https://issues.apache.org/jira/browse/CAMEL-20534
> Project: Camel
> Issue Type: Improvement
> Components: camel-grpc
> Reporter: James Netherton
> Assignee: James Netherton
> Priority: Minor
> Fix For: 4.4.1, 4.5.0
>
>
> The gRPC docs are maybe a bit misleading because they state that the port
> part of the URI is mandatory.
> However, it's currently possible to omit it and you then end up with either a
> consumer started on a random port (because the port int has the default value
> of 0). Or a producer that tries to connect to the gRPC default port.
> So I propose to initialize the port with a default of -1 and fix up the
> validation logic as using isEmpty is not really appropriate in this case.
