Corrected logic of setting additional authorization attributes to avoid ClassCastException as they are returned as Map by CheckTokenEndpoint.
Response code for un-authenticated access to /oauth/token endpoint

A change in 1.4.3 added bearer token access to the token endpoint, but the
request matchers were overspecified so access without an Authorization
header was dropping through to the default login entry point (instead of
the OAuth one).

[Fixes #57751368] [cfid-805]
Updated UAA version to 1.4.6
Merge branch 'release/1.4.6'
