Good catch! This is definitely a bug that I introduced as a part of SOLR-16393 - sorry for the trouble.
The problem, counter-intuitively, is this line. [1]. The annotations in this file are overriding the ones we need in 'DeleteAliasApi' (which is where the path and verb are specified). I'll get this fixed and backported for 9.4.1/9.5. I imagine it's cold comfort, but I really appreciate you guys trying out the v2 APIs and catching bugs - sorry it ended up burning you guys this time.
