ant task mail fails on jdk10

[Simon IJskes - QCG]

As bugzilla is unreachable for now:

     <target name="_testmail" >
         <mail mailhost="mail" mailport="25" from="[hidden email]"
subject="Testemail"  >
             <to address="[hidden email]" />
         </mail>
     </target>

$ JAVA_HOME=/usr/lib/jvm/java-8-oracle/ ~/opt/apache-ant-1.10.4/bin/ant
_testmail

runs ok.

_testmail:

JAF has been removed from Java 10, so now you need to provide its
replacement https://github.com/javaee/activation when starting Ant.

I don't really think we need to change anything inside of Ant but should
document the fact and likely add something to the FAQ in addition to the
mail task's manual page.

We already have something:
mail: "This task may depend on external libraries that are not included in
the Ant distribution. See Library Dependencies for more information."
dependencies:
"mail.jar Mail task with Mime encoding, and the MimeMail task
http://www.oracle.com/technetwork/java/index-138643.html
 activation.jar Mail task with Mime encoding, and the MimeMail task
http://www.oracle.com/technetwork/java/javase/jaf-135115.html"

mail.jar could be downloaded via "ant -f fetch.xml javamail", but activation
has to be installed.


So what changed with Java10?

Did my own test:

     <mail mailhost="${mail.host}" user="${mail.user}"
password="${mail.pwd}" from="${from}" subject="Testemail">
         <to address="${to}"/>
         <message>
            Ant-Version:  ${ant.version}
            Java-Version: ${java.version}
         </message>
     </mail>

Running with Java8 + Java10, and I got my two mails:

            Ant-Version:  Apache Ant(TM) version 1.10.1 compiled on February
2 2017
            Java-Version: 1.8.0_171

respectively

            Ant-Version:  Apache Ant(TM) version 1.10.1 compiled on February
2 2017
            Java-Version: 10.0.1


I contrast to my last mail, I could install activation via fetch.xml.
I had run "ant -f fetch -Ddest=system" before.

libraries.properties for Ant 1.10.x specify javax.mail 1.6.1 which pulls in
activation 1.1

Well at least we should update the links :-)

Given javax.activation has been part of the core lib for a few releases
(IIRC it was added in Java6 and now gets removed again) people will not
have installed it and now are caught by surprise. Therefore I suggest to
create a FAQ entry for it and add an additional hint to the mail task
manual.

> So what changed with Java10?

The blurb about activation.jar being an external library has become true
again. It is false when using Java6 to 9.
