>             Project: Camel
>          Issue Type: Bug
>          Components: camel-jetty
>    Affects Versions: 2.16.5, 2.17.5, 2.18.2

> In JettyHttpComponent, "createHttpClientTransport" method the number of selectors is derived by:
> {noformat}
> int selectors = Runtime.getRuntime().availableProcessors() / 2;
> {noformat}
> If the number of available processors is 1, divided by 2, cast to int is 0 which causes an IllegalArgumentException.
> The safe way to do this is via Math.max, like the Jetty code does:
> {noformat}
> int selector = Math.max(1, Runtime.getRuntime().availableProcessors() / 2);
> {noformat}
> As per the code this is only exercised when maxThreads is not null, otherwise the default constructor is called and selectors are created properly.
