does not works with java 17

[dimitriy-k]

please update to the latest swagger-codegen, where they fixed the issue:

swagger-api/swagger-codegen#10966

it gives now error:

Caused by: com.github.jknack.handlebars.HandlebarsException: /handlebars/typescript-angular/licenseInfo.mustache:2:6: java.lang.reflect.InaccessibleObjectException: Unable to make public boolean java.util.Collections$EmptyMap.isEmpty() accessible: module java.base does not "opens java.util" to unnamed module @3c60b7e7

to fix it, I have to call it now with extra options:

`_JAVA_OPTIONS="--add-opens=java.base/java.util=ALL-UNNAMED" swagger-codegen-cli generate ...

I have the same problem. I could workaround it by upgrading handlebars, a swagger-codegen dependency.

            <plugin>
                <groupId>io.swagger.codegen.v3</groupId>
                <artifactId>swagger-codegen-maven-plugin</artifactId>
                <dependencies>
                    <dependency>

                        <artifactId>handlebars</artifactId>
