Does FTPClilent commons-net:3.9.0 not supported on Android 7 and below?

Question

I am using Apache Commons Net to download files through FTPClient. There is no problem when using version 3.8.0.

But after upgrading to 3.9.0 the app crashing on instantiating the FTPClient with the below stacktrace:

The DownloadService.kt:188 points to the constructor onf FTPClient(), while FTPClient.java:544 points to private Duration controlKeepAliveTimeout = Duration.ZERO;.

Also noticed that the constructor of the FTPClient in 3.9.0 version uses java.time API which is supported in API 26+.

Dependency used:

implementation("commons-net:commons-net:3.9.0")

Is there anyway to upgrade to 3.9.0 version or just stuck with the 3.8.0 version for supporting Android 7 and below?

Thanks!
