Sometimes you cannot reload the server using the management interface. This happens when the server is shutdown before it responds to the client, resulting in an IOException. This can also happen during installation, which can result in the installation process failing.

Full stacktrace from server

Description of problem:
There is an issue when reloading server via management interface. The root issue is that, the server is shutdown before it responds to the client, effectively resulting in IOException complaining 'Channel closed'.

It is reported for EAP in the BZ which is blocking this one.

We encountered the issue in two cases:
1. reloading the server explicitly via cli operation
2. during installation of the server

The use case 2. is more problematic, as it fails the installation.
As noted in the linked BZ, it has not been resolved on the server, but can be solved on client side. This approach might be adopted in the DV installer.

See both full server stacktrace and its appearance in installer logs in the attachements.
