The following example includes an incorrect PURL:

https://github.com/aboutcode-org/vulnerablecode-ai-experiments/blob/9f08bcbdccc381ce885446db6e0afbf29059db87/test.py#L22:L25

However, apr-util is not a valid Maven package. The test should be updated to use the correct PURL or removed. A more accurate identifier might be something like pkg:apache/apr-util or another ecosystem-specific PURL, depending on how the project is distributed.
