Viacheslav Kabanovich commented on JBIDE-21795:
-----------------------------------------------

In fixing JBIDE-21803, I will make ICredentialDomain.getName() never to return null - this value is used by UI in many places and most of them do not allow null. To avoid multiple checks for null everywhere, it is better to return empty string. So, there will be pull request to JBIDE-21803 that will fix both issues.
