[resolved] error with tSendMail (Network is unreachable) but works in debug mode!

[soowork]

Hi all,
I am using Enterprise Data Integration 5.2.2.r99271. I am working locally on my Windows development PC.
I have a job (which works) and I am trying to add a tSendMail as the last step in the job flow. I am using my correct mail server and port (25) in the tSendMail component. I am able to ping/telnet to the SMTP server.
When I run my job in basic mode I get the following error and no email is sent:

javax.mail.MessagingException: Could not connect to SMTP host: mailhost.points.com, port: 25;
nested exception is:
java.net.SocketException: Network is unreachable: connect

When I run the SAME job in Java Debug mode, it works - no error and email is received!
I have closed and re-opened Talend Studio. I have deleted and re-created the tSendMail component. Same problem.
Does anyone have any suggestions for me? TIA
Sue

OK, we found the issue - see https://community.talend.com/t5/Design-and-Development/tSendMail-and-Java-1-7/td-p/110957
When I downgraded to Java runtime 1.6 from 1.7, the problem was resolved.
