Brian Stansberry commented on WFLY-10222:
-----------------------------------------

The fix for this JIRA is basically a workaround that prevents a more critical problem -- the inability to read a large resource tree due to a relatively unimportant failure in a small piece -- by introducing a different bug: ignoring a failure, even when it occurs in a narrow context where the failure is *not* relatively unimportant.

I believe the benefit of the workaround fix outweighs the cost of adding the different bug. But it should be understood that the added bug is a bug, and that an overall fix that adds the correct behavior and removes the workaround should not be considered to be a regression, even if some use cases that work with the workaround to now break.

See WFCORE-3754 for further details. The proposal there would basically require some sort of input from the client in order to ignore failures. The expectation is the console would provide that input when appropriate for its requests. Other clients, e.g. the CLI executing a low level operation, would not.

The original report here is about web console usage. So long as the web console usage is not broken in any permanent fix, that should mean there is no regression introduced by the permanent fix.

> I have installed wildfly 12.0.0 final, or it says the file name I just downloaded from your site. It was working perfectly. After a while, I just installed Keycloak server 3.4.3 and the corresponding adapter for wildfly. From this moment on, every time I access to my local installation of wildfly through the web console I cannot see my deployments anymore, it returned the following error:

> I have read that this is a known issue and can ignore it; this thing is every time I need to modify or redeploy something I have to remove the corresponding tag from standalone.xml and restart wildfly server. Anyway it's working in local environment but a I have to set the production wildfly server by installing Keycloak server and its adapter and I don't know if this is going to break something; considering the wildfly is already installed (same version as mine) and working properly, but without keycloak.
