Tests never exercise @{baseVersion}@ used in DEFAULT constants #64

Description

Both DEFAULT_FILE_NAME_MAPPING and DEFAULT_FILE_NAME_MAPPING_CLASSIFIER use @{baseVersion}@ in their expressions (MappingUtils.java:72,78). However, every test in MappingUtilsTest.java uses @{version}@ in its expressions instead.

Risk

There is no test coverage verifying that @{baseVersion}@ resolves correctly, or documenting the behavioral difference between baseVersion and version.

Suggestion

Add at least one test that evaluates a mapping expression containing @{baseVersion}@ to ensure it resolves as expected.
