Version Distance Policy Evaluation Cannot Deal With Letters

[msymons]

Current Behavior

As a result of logging improvements introduced in v4.9.0 via Issue #2979, a Version Distance Policy that attempts to evaluate a component that contains a letter in the version (either existing version or latest version) will generate an informative WARN:

Steps to Reproduce

1. Create version distance policy. This was the policy that gave rise to exceptions reported above but a better test would be to have version value as 1 rather than 2.

2. Upload BOM containing following components....
   pkg:maven/jakarta.annotation/jakarta.annotation-api@1.3.5?type=jar
pkg:maven/org.apache-extras.beanshell/bsh@2.0b6?type=jar

Expected Behavior

1. No WARN exceptions logged per current behaviour.
2. Assuming policy distance is 1, a policy violation for pkg:maven/com.google.code.findbugs/annotations@2.0.1?type=jar as this is one major version behind latest version
3. Valid policy violations for any other component in project that is more than one version out of date. Currently I am not seeing any Version Distance policy violations for the project under test... but have not tested against a project that contain NO components that would give the WARN exception.
