Donald Whytock updated CAMEL-4161:
----------------------------------

    Attachment: new_SpringJavaMailSender.java
                new_MimeMessagePreparator.java
                new_JavaMailSender.java
                new_DefaultJavaMailSender.java
                MailProducer.java
                MailEndpoint.java
                MailConsumer.java
                MailConfiguration.java
                diff_MailProducer.java
                diff_MailEndpoint.java
                diff_MailConsumer.txt
                diff_MailConfiguration.txt

JavaMailSender.java and MimeMessagePreparator.java are local versions of these two interfaces.  

SpringJavaMailSender.java is a wrapper class that extends the Spring JavaMailSenderImpl and ties it to the local interfaces.  

DefaultJavaMailSender.java performs the functions of a sender if the Spring sender isn't available.

The modified MailConfiguration.java attempts to instantiate SpringJavaMailSender, and, on failure, instead instantiates DefaultJavaMailSender.

Changes to the other classes tie them to the local JavaMailSender interface.

These should be accompanied by a change to the Maven configuration, so that the dependency on org.springframework.mail.javamail is optional.

> camel-mail is currently dependent on org.springframework.mail.javamail.JavaMailSenderImpl, but uses relatively little of its functionality.  In many cases it may be sufficient to fall back on a default JavaMailSenderImpl that only implements the bare minimum necessary to send mail, similar to how Management functionality falls back on DefaultManagementStrategy if the Spring JMX implementation is not available.
> This would make camel-mail use possible in an otherwise Spring-less application.
