I don't believe this is possible on either QFX or EX switches, however it is definitely possible on the ACX5000, any of the branch SRX platforms and the MX series.

Hi, RSTP blocking the port probably suggests presence of a loop since RSTP has a single STP instance and would look at BPDUs from VLAN1 only and completely STP block the port [all VLANs inclusive] if...

IMO, it could be or could as well not be JUNOS version related. JTAC would be best placed to answer.Would advise to save the support bundles for the later JTAC case. However, the logs do hint towards...
