Description of Change

• Previously, this analyzer processed all file types, which contradicted its JavaDoc stating a focus on JAR files.

Pull request overview

This PR aligns VersionFilterAnalyzer’s behavior with its JavaDoc and issue #8356 by limiting it to operate only on JAR files, using the file-type analyzer mechanism already used across the core analyzers.

Changes:

• Updated VersionFilterAnalyzer to extend AbstractFileTypeAnalyzer and added a .jar FileFilter via FileFilterBuilder.
• Implemented getFileFilter() and prepareFileTypeAnalyzer(...) to conform to the AbstractFileTypeAnalyzer contract.
• Added a unit test ensuring only .jar files are accepted by the analyzer.
