[jira] [Commented] (FREEMARKER-177) freemarker Configurable has a asymmetric settings get/set which causes spring failure

Dániel Dékány commented on FREEMARKER-177:
------------------------------------------

How do I recreate this issue? I have tried many things. Java 8 and Spring Boot Starter 2.6.0, 2.7.0, and 2.7.6. Also with Java 11 and 2.7.6. Also Java 17 and Spring Boot Starter 3.0.0 and Java 17. I have defined a {{freemarker.template.Configuration}} bean in a {{@Configuration}} class, that simply creates it with the constructor, and then I get that bean with {{ApplicationContext.getBean}}. Then I did the same with XML configuration and 2.7.x, and I have even set the {{settings}} property to a {{Properties}} object in the XML. All the combinations worked.

As a side note, Java's {{BeanIntrospector}} has no problem with that property. It just says that the {{setting}} property has type {{Map}} (the common ancestor class of {{Map}} and {{Properties}}), and both a read method, and a write method. But, that's not the point. I need to make Spring to fail in order to find the most backward compatible workaround.

> When I try to configure freemarker.template.Configuration in spring, it throws the exception: 
> {{Caused by: org.springframework.beans.FatalBeanException: Failed to obtain BeanInfo for class [freemarker.template.Configuration]; nested exception is java.beans.IntrospectionException: type mismatch between read and write methods}}
> The problem is that setSettings(...) takes a Properties and getSettings() returns a Map.  The get has been deprecated forever.   Can it please be fixed?  The alternative is having to do some spring hackery.
