Enquiry on commons-net 3.9

[Toh Min]

Hi,
I have an application running on Java 1.7 which may be using commons-net. I saw 
from the website that commons-net 3.9 requires Java 1.8.
I would like to resolve CVE-2021-37533 for commons-net, is there anything which 
I can do to mitigate it since the java version which I am using is lower than 
the minimum version for commons-net 3.9.
Thanks & Regards,
Min
