Unable to configure ThreadPoolSize in java processor from cm:property file.

Issue

• Unable to configure ThreadPoolSize in java processor from cm:property file
• I am trying to initialize a ExecutorService in camel Processor, something like

public TransformProcessor(int a) throws JAXBException {
        this.threadPool = Executors.newFixedThreadPool(a);

    }

• I want to inject value of threadpool size from a property file so that I dont need to change code again and again.
