Hi,

During testing I found out some problems with sending emails with
Karaf 4.3.6 As far as I know version 4.3.3 is working. So I tried
4.3.4 and unfortunately this one it not working either. When I tried
to send email I could see this exception:
javax.mail.MessagingException: IOException while sending message
    at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1350)
~[?:?]
    at javax.mail.Transport.send0(Transport.java:231) ~[?:?]
    at javax.mail.Transport.send(Transport.java:100) ~[?:?]
...

I checked some differences between 4.3.4 and 4.3.3. I  found out that
the exception was gone when I removed line
javax.activation;version="1.2.1"  (jre-9 section)
from jre.properties.
I also checked all activation bundles that we have got:
 76 │ Active   │  80 │ 1.2.1.3               │ Apache ServiceMix ::
Specs :: Activation API 1.2.1
145 │ Active   │  10 │ 1.2.2                 │ Jakarta Activation

Does anybody know what is wrong? Or is there anything that needs to be
done (updated/reconfigured) for Karaf 4.3.6?

Thanks in advance

Jakub
