Do we know when the last time it was that this worked? I cannot recall much changing in the installer recently that would have caused this.

Comment 4 John Mazzitelli 2017-05-03 17:53:57 UTC

It's all coming back to me now :)

This is a "CAN'T FIX" BZ. EAP6 does not allow custom extensions to be installed inside of it (that was a feature that was added to EAP7+).

Thus, the agent cannot be installed in EAP6 because it simply cannot run inside of EAP6. This is true for any subsystem extension - not just the agent. EAP6 did not support running custom subsystem extensions.
