[INFO] Done SpotBugs Analysis....

[INFO] <<< spotbugs:4.8.6.6:check (default-cli) < :spotbugs @ commons-io <<<
```
To reproduce:
```
git checkout https://github.com/apache/commons-io.git
cd commons-io
git checkout adc6574c2125035fe95a5a80db08995f8d60459c
mvn -Dcommons.spotbugs.impl.version=4.9.0 clean compile spotbugs:check
```
This worked fine in 4.8.0.

Focus on implementing the required functionality correctly and efficiently. Treat this as a programming challenge.
