False positives in Eclipse Hawkbit

[hanna-modica]

Description

ScanCode reports BSD 3 Clause in multiple Eclipse Hawkbit classes, although it states Eclipse Public License v1.0.

Examples:

• hawkbit-ui/src/main/java/org/eclipse/hawkbit/ui/common/event/FilterType.java line 4-15
• hawkbit-ui/src/main/java/org/eclipse/hawkbit/ui/common/data/aware/DsIdAware.java line 4-14
• hawkbit-ui/src/main/java/org/eclipse/hawkbit/ui/utils/SPUITargetDefinitions.java line 4-17

and many more

How To Reproduce

Scan https://github.com/eclipse/hawkbit with ScanCode

System configuration

The scan was done on Linux with the OSS Review Toolkit https://github.com/oss-review-toolkit/ort/ using ScanCode as the scanner.

Thanks!
The culprit is a rule edl-1.0_or_epl-1.0.RULE and edl-1.0_or_epl-1.0.yml that should be detected only if there is more of it detected using the "minimum_coverage" attribute likely to about 90%
