wildcards in url lead to error during asciidoc generation

https://github.com/OpenAPITools/openapi-generator/blob/90eacb685c57308e67c65e436b19d160091f91e1/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AsciidocDocumentationCodegen.java#L178

using wildcards in my api path e.g. /unitcheck/v2/houses/{houseId}/** leads to this

Start at modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AsciidocDocumentationCodegen.java#L178 and reproduce generation with a path ending in /**. Trace how that path becomes the supporting file destination, then verify that generation completes without InvalidPathException and produces the expected Asciidoc output.
