handy tip on how to increase jetty HttpClient threadpool size in ServiceMix 3.2.2

I was recently working on some jetty related issue in Servicemix 3.2 and got Servicemix people to update servicemix-http component to have configurable jetty httpClient thread pool size. Before I forget it I wanted to make a note of it so adding this entry.

In Servicemix 3.2.2 and onwards jetty HttpClient threadpool can be configured using following entry in component.properties file.
servicemix-http.jettyClientThreadPoolSize=33

Also, you can configure Servicemix to use Jetty httpClient per httpProvider (by default a single client is shared among all httpProviderEndpoints) by adding

servicemix-http.jettyHttpClientPerProvider=true

Also from ServiceMix 3.2.2 onwards Jetty HttpClient uses nio channel selector implementation of jetty. (previously it was using socket connector which was blocking I/O and was causing thread locking in thread pool in some stress conditions)
