Symptoms

After recently upgrading to BPM / SOA Bundle Patch 11.1.1.7.5, the human task email notifications do not contain body content due to the HTTP port being used instead of HTTPS.

In the logs you might see the following errors:

Steps to replicate the issue involve configuring https for the task by modifying the task Administration properties in enterprise manager.  https is enabled simply by setting the https port, as soa should prefer https over http.

Changes

This happens in an environment where SSL is enabled and the human task has been configured with an HTTPS port.

The first error Unsupported protocol: https'  actually occurs because the email is being generated via http, goes out to a load balancer, and the traffic is redirected to https (which is not supported per weblogic KM 1302973.1)

The second error occurs because again the email is being generated via http, but the http port isn't available.

In both situations the problem is that it is generating the email content using http when you have actually configured https.  This is related to bugs:
19674030 - Error getting email content for default todo task
17412297 - INITIATOR AND TASK IN INBOX HAVE DIFFERENT PRECEDENCE OF HTTP/HTTPS PROTOCOLS
