I have Confluence/JIRA latest versions (self hosted). Confluence gets its users from JIRA. I created a new topic and then used the Tools/Share option to notify all of the new topic. I used "jira-users" to send the message to. It sent to everyone including disabled users. I would expect the behavior to NOT send to disabled users.

Steps to Reproduce in Confluence:

1. Create a user, and set to 'Disabled'
2. Create a group and make this user a member of this group
3. Share a page with the group
   This results in an email being sent to the inactive user

Steps to Reproduce with a Crowd server handling user management:
Same as above, but with the user and group coming from Crowd. Note that the equivalent of 'disabled' is 'inactive'.
