[SLING-8254] Connecting to a Sling Server does not allow cancelling the operation

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

When connecting to a remote server with poor connectivity there are two problematic issues:

1. there is no timeout, so the connection stalls forever
2. there is no way to cancel as it's apparently not propagated from the UI

This, together with the around the repository map means that connecting to servers is not possible unless Eclipse is restarted or a long time (minutes?) is elapsed.
