Following publishers does not work correctly when contained in Flexible Publish plugin.

• Publishers that do not use DataBoundConstructor annotation for their constructors.
  • E-mail Notification ( hudson.tasks.Mailer at least in Jenkins 1.425)
    • Fails to save the project configuration.
  • These publishers are automatically filtered by current implementation.
• Publishers that have their own Descriptor#newInstance.
  • Publish JUnit test result report hudson.tasks.junit.JUnitResultArchiver.
    • Fails to store configurations extended with TestDataPublisher. It is stored in Descriptor#newInstance, but not in the constructor.
    • For example, JUnit Attachments Plugin
  • Cobertura Plugin
    • Fails to store "Coverage Metric Targets", which is stored in Descriptor#newInstance.
  • RunDeck Plugin
    • Fails to store "Job ID", which is stored in Descriptor#newInstance(Also stored in the constructor, but the field name is mismatched).

I try to handle Descriptor#newInstance.
