From Hung For this issue, I believe it’s because we now compile server code with 1.5 and when you specify jdk1.4 to run weblogic, it doesn’t match.

Not an easy fix unfortunately. To fix, you would need to specify both 1.4 and 1.5 in the session configurator to run the demo, which is currently not supported.

Do we want to do anything about this? Or can we kill WL 8 support?

The workaround is to use a later version of WL.
