Failed to convert valid RDF type SBOM into another format

Description

There is a failure in converting the valid RFD type SBOM into another format.

During verification, it produces some license-related warnings but confirms that the SBOM is valid. However, it results in an error during conversion:

Error converting: Error converting SPDX file: class java.lang.RuntimeException org.spdx.spdxRdfStore.SpdxRdfException: http://spdx.org/rdf/terms#isDeprecatedLicenseId was not found related to class http://spdx.org/rdf/terms#ListedLicenseException

Steps to reproduce

1. Download the SBOM zip and extract it -
   nginx_1.27-spdx-1.zip
2. Verify the SBOM
   java -jar ./tools-java/target/tools-java-2.0.1-jar-with-dependencies.jar Verify /Downloads/nginx_1.27-spdx-1.rdf
3. Convert sbom into JSON format
   java -jar ./tools-java/target/tools-java-2.0.1-jar-with-dependencies.jar Convert /Downloads/nginx_1.27-spdx-1.rdf test.json

Iniziare con le invocazioni da riga di comando Verify e Convert di tools-java descritte nell’issue, utilizzando come input il file allegato nginx_1.27-spdx-1.rdf. Tracciare l’errore di conversione che coinvolge isDeprecatedLicenseId e ListedLicenseException, quindi confermare che la conversione di questa SBOM RDF valida in JSON venga completata correttamente senza l’errore segnalato.
