Hey Chris,

there is no code in Undertow or Wildfly (as you cross posted also there)
that would throw error you are describing.

Are you sure error is coming from Undertow / WildFly code and not from some
other source?
I would look for any filters that might be added to your application that
could influence that.

Undertow itself supports PATCH command without any issues.
It would also come a surprise to me that no one would notice till now given
that PATCH is one of quintessential methods in modern REST applications.


cheers,
tomaž
