org.apache.nutch.indexer.IndexingFiltersChecker.run(String[]) invokes System.exit(...), which shuts down the entire virtual machine

Invoking System.exit shuts down the entire Java virtual machine. This should only been done when it is appropriate. Such calls make it hard or impossible for your code to be invoked by other code. Consider throwing a RuntimeException instead.
