open api generator oneof problem

Description

Trying to get the java code out of this json:

"xComponents": {
        "type": "array",
        "title": "This is a title",
        "items": {
          "oneOf": [
            {
              "$ref": "xComponent.AAA.schema.json"
            },
            {
              "$ref": "xComponent.BBB.schema.json"
            },
            {
              "$ref": "xComponent.CCC.schema.json"
            },
            {
              "$ref": "xComponent.DDD.schema.json"
            }
          ],
          "type": "object"
        },
       "minItems": 1
      }

But It generates this list wierd class name that cannot get build:

private List<OneOfxComponentAAASchemaJsonxComponentBBBSchemaJsonxComponentCCCSchemaJsonxComponentDDDSchemaJson> xComponents = new ArrayList<OneOfxComponentAAASchemaJsonxComponentBBBSchemaJsonxComponentCCCSchemaJsonxComponentDDDSchemaJson>();

Can someone help me with this please?

Start by reproducing the Java generation from the provided schema, focusing on the array item that contains the oneOf references. Trace how the Java generator constructs the combined model name and confirm that the generated declaration compiles; the issue is done when this schema produces valid Java code with a usable oneOf type.
