Also, I agree. We don't want to break anything for current users. If the
expected behavior changes, we don't know how that impacts current users,
because some may be relying on this to fail.

> Key: NIFI-4326
> URL: https://issues.apache.org/jira/browse/NIFI-4326
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.3.0
> Environment: jdk 1.8.0_121-b13
> Reporter: Benjamin Wood
> Priority: Minor
> Fix For: 1.4.0
>
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> 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.
