    ** Module   : PathResolverContainer.java
    ** Abstract : PathResolverContainer resolves a legacy system absolute file path into its host
    **            system file path by the dedicated path resolved and logs calmly if a given path
    **            can't be resolved.

    ** 001 SBI 20180522 It catches unresolved path exceptions and logs them at the Level.FINER.
    ** 002 ECF 20180613 Performance fixes. Avoid constructing log message text when not logging;
    **                  minimize overhead of log level check.
    ** 003 GBB 20230512 Logging methods replaced by CentralLogger/ConversionStatus.
