OpenAPI 3.1.0 - $ref with json path with esaping in it throws URISyntaxException

[ilya-anodot]

I just tried switching my project to OpenAPI 3.1.0 version and found that any $ref with json path with escaping in it fails with

java.net.URISyntaxException: Illegal character in fragment at index 46: ./some_folder/API.json#/paths/~1path-in-json~1"
    at java.net.URI$Parser.fail (URI.java:2976)

    at io.swagger.v3.parser.reference.ReferenceVisitor.visitPathItem (ReferenceVisitor.java:108)

My $ref looks like this: "$ref": "./some_folder/API.json#/paths/~1path-in-json~1".
Inside the target file it points to element:

{
   "paths" :{
        "/path-in-json/" : {
            ...
        }     
   }
}

This worked perfectly in version 3.0.3 and stopped working since I tried changing to new version. I'm using

<plugin>
  <groupId>org.openapitools</groupId>
  <openapi-generator-maven-plugin</artifactId>
  <version>7.8.0</version>
