>    Affects Versions: 1.3.0
>         Environment: jdk 1.8.0_121-b13
>            Reporter: Benjamin Wood
>            Priority: Minor

> The ExtractEmailHeaders  processor throws a NullPointerException if there is no TO, CC,
and BCC recipients.
> If there are no recipients "originalMessage.getAllRecipients()" returns NULL, and not
a 0 length array.
> If an address is empty (<> or " ") then getRecipients() will throw an "Empty Address"
AddressException
> It's possible this is only an issue with Oracle Java.
