    [ https://issues.jboss.org/browse/WFCORE-993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123422#comment-13123422 ] 

Brian Stansberry commented on WFCORE-993:
-----------------------------------------

Quick design documentation comment on the fix for this:

The CLI and the server now require that "admin-only=true" be set when a reload is performed of an embedded host controller. This is either via the "--admin-only=true" param to the high level CLI reload command, or a "admin-only=true" param to a low level operation.

It's not particularly user-friendly forcing users to type this instead of defaulting to 'true'. But in all other cases the default for this is 'false', and correctly so, as reloading to an admin-only process is not the stardard use case.  You start in admin-only and reload out of it to get your changes into the runtime.

In the future we want to support using admin-only=false with an embedded HC. When we do that, if the CLI when executing a reload has been defaulting --admin-only=true without requiring user input, then we either have to maintain that behavior, which is unintuitive and inconsistent with all other reload use cases, or we change default behavior possibly breaking existing scripts that relied on the default. To avoid that future incompatibility problem, we decided to force users today to explicitly declare --admin-only=true.
