Generation Details

language: java
library: jersey2 or jersey3

Steps to reproduce

1. Save the file above as openapi.yml
2. Execute docker run -v `pwd`:/temp -it openapitools/openapi-generator-cli:latest generate -g java -i /temp/openapi.yml -o /temp/build/ --library=jersey3
3. Look at the content of the generated file build/src/main/java/org/openapitools/client/api/DefaultApi.java

Current:

    // Path parameters
    String localVarPath = "/resources/{uri}"
            .replaceAll("\\{uri}", apiClient.escapeString(uri));

Expected

    // Path parameters
    String localVarPath = "/resources/{uri}"
            .replaceAll("\\{uri}", apiClient.escapeString(uri.toString()));

Other details

This is working fine targeting the library okhttp-gson and the output is

        // create path and map variables
        String localVarPath = "/resources/{uri}"
            .replace("{" + "uri" + "}", localVarApiClient.escapeString(uri.toString()));

[wing328]

        String localVarPath = "{{{path}}}"{{#pathParams}}
            .replace("{" + "{{baseName}}" + "}", localVarApiClient.escapeString({{#collectionFormat}}localVarApiClient.collectionPathParameterToString("{{{collectionFormat}}}", {{{paramName}}}){{/collectionFormat}}{{^collectionFormat}}{{{paramName}}}.toString(){{/collectionFormat}})){{/pathParams}};

that's from okhttp-gson api.mustache (modules/openapi-generator/src/main/resources/java/libraries/okhttp-gson/api.mustache)

to fix it, we will need to add the toString() method.

is that something you can help us with by filing a PR to update the following?
