> I found the below issues for Jackson and ClassGraph (formerly known as
> FastClasspathScanner) which suggest using FastClasspathScanner 2.6.1+ will
> resolve this issue:

> [https://github.com/FasterXML/jackson-databind/issues/2512#issuecomment-543992179]
> [https://github.com/classgraph/classgraph/issues/141#issuecomment-331620813]
> A temporary workaround is for me to override the FastClasspathScanner
> dependency to 2.6.1 in my project:
> {code:xml}
> <plugin>
> <groupId>org.apache.jackrabbit</groupId>
> <artifactId>filevault-package-maven-plugin</artifactId>
> <version>1.1.0</version>
> <dependencies>
> <dependency>
> <groupId>io.github.lukehutch</groupId>
> <artifactId>fast-classpath-scanner</artifactId>
> <version>2.6.1</version>
> </dependency>
> </dependencies>
> </plugin>
> {code}
> Attached is an example Maven project to reproduce the issue with
> org.apache.jackrabbit:filevault-package-maven-plugin:1.1.0.
