Story Points:2
When a repository is deleted, it is marked as such by renaming it to an obscure name in the database. This renaming will allow an end user to avoid referential integrity issues should they wish to create a new repository with the same name.
When scheduled tasks run against "All Repositories", the list may include these obscurely named deleted repos. An example where this was seen in practice is in the following logging in Nexus 3.7.1 at startup:

Expected
Mainly the NullPointerException should not happen.
Since deleted repos are effectively "gone" - tasks should not be able to retrieve a list of repositories that includes deleted repositories by default. If there is a valid use case for processing deleted repos with a task, the task should explicitly handle asking for a list which may include them ( although I am unaware of such use case at this time ).
