[BUG] [JAVA] Unused Import Requires Its Own Dependency

[palatam]

openapi-generator version

Affects all versions (tested 6.6 to latest 7.4).

Description

Using:

<generatorName>java</generatorName>
<library>apache-httpclient</library> or <library>resttemplate</library>

The generated ApiClient.class imports an unused Type import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider; which is not used but requires an additional Dependency to even compile.
