Sending vendor content type with jMeter throws IllegalArgumentException

I need to add a custom content-type to a file uploaded with a multipart request. To do this, I put vendor content-type application/vnd.anything.process+json;ver=1 as a MIME type for this file. Unfortunately, jMeter throws IllegalArgumentException, because it recognizes ; as an invalid character in the content-type specification.

If this is not supported, then how to send a file with a content-type that contains ;? I tried to use a postman and record outgoing HTTP call from jMeter, but it fails with the same exception.

enter image description here
