Seen this bug in Java client generation but I think its broken for multiple languages.

Description

properties that set a default but references an enum type using allOf results in incompilable java client code.

openapi-generator version

regression since 6.3.0 (probably since #14130 was merged)

Generation Details

openapi-generator-cli generate -i default-for-referenced-enum.yaml -g java -o enum-issue

results in TestPostRequest.java with line 54 being:

private TestEnum test = Bar;

instead of

private TestEnum test = TestEnum.BAR;

Steps to reproduce
