Verifies the integrety of the projects, as builds are executed immediately after a code change was detected. This plan provides no artifiacts (use a nightly build instead).
However, previous versions of XEP-0045 specified an additional <x
xmlns='jabber:x:conference'> element to be included (see
implementation note in XEP-0045). Therefore, a legacy implementation
may emit a mediated invitations in the form of
Unfortunately, this matches
MultiUserChatManager.DIRECT_INVITATION_FILTER because
GroupChatInvitation matches <x xmlns="jabber:x:conference"/>. However
the message is not a direct invitation but a mediated one. Besides
this invoking the wrong listeners (direct vs. medidated) the value for
'inviter' that's used to invoke that listener will be false.
To fix this, extend DIRECT_INVITATION_FILTER with
NotFilter.of(MUCUser.class) to avoid matching those legacy mediated
invitations.
