Troubleshooting
Problem
When TDI 7.1.1 or SDI 7.2 use IBM JRE 7 the following exception will appear, when either system.sendMail() or SendEMailFC are used to send email.
Symptom
On Assemblyline execution, the system.sendMail() produces the following error:
DEBUG SMTP: trying to connect to host "na.relay.ibm.com", port 25, isSSL false
CTGDIS399I Unable to send mail.Exception occurred: javax.mail.MessagingException: Could not connect to SMTP host: na.relay.ibm.com, port: 25;
nested exception is:
java.net.SocketException: Network is unreachable: connect
On Assemblyline execution, the SendEMailFC produces the following error:
javax.mail.MessagingException: Could not connect to SMTP host: 10.10.10.1, port: 25;
nested exception is:
java.net.SocketException: Network is unreachable: connect

Caused by: java.net.SocketException: Network is unreachable: connect
Cause
It's possible IBM JVM 7 is defaulting to the IPv6 protocol.
Resolving The Problem
Available options to implement:
In the solution.properties file, find, un-comment, and set 'java.net.preferIPv4Stack=true'
or
Call system.setProperty("java.net.preferIPv4Stack" , "true") before calling system.sendMail()
or
In the SendEMailFC / After Initialize Hook, add system.setProperty("java.net.preferIPv4Stack" , "true")
