Multiple false-positive findings in flyway-core

[MarcelBochtler]

Description

Scanning flyway-core with ScanCode 30.1.0 results in multiple findings of LicenseRef-scancode-proprietary-license which IMO are false-positives.

The matched lines are in all package-info.java files lines 14-17:

 * limitations under the License.
 */
/**
 * The main Flyway package and for most users, the only one they'll ever need to know about.

Another LicenseRef-scancode-proprietary-license finding which is also a false-positive finding is in org/flywaydb/core/Flyway.java lines 350-366:

         throw new org.flywaydb.core.internal.license.FlywayTeamsUpgradeRequiredException("undo");













    }

    private CleanResult doClean(Database database, SchemaHistory schemaHistory, Schema defaultSchema, Schema[] schemas, CallbackExecutor callbackExecutor) {

How To Reproduce

Scan flyway-core with ScanCode 30.1.0.

System configuration

I scanned flyway-core using the latest ORT version on Linux.
