It looks like it's not finding any files. Here is the code thats failing: https://github.com/apache/lucene-solr/blob/35d8e3de6d5931bfd6cba3221cfd0dca7f97c1a1/solr/core/src/java/org/apache/solr/util/SolrLogPostTool.java#L126
A couple of things to note: postlogs should only be run on log files. So if there are different types of files in the directory it's pointed to it will have unexpected behavior. So you can run it on a single log file, or a directory containing only log files.
