[infinispan-issues] [JBoss JIRA] (ISPN-1727) ComponentMetadataPersister is using dangerous characters in regular expression replacement

ComponentMetadataPersister is using dangerous characters in regular expression replacement ------------------------------------------------------------------------------------------ Key: ISPN-1727 URL: https://issues.jboss.org/browse/ISPN-1727 Project: Infinispan Issue Type: Bug Affects Versions: 5.1.0.CR3 Reporter: Sanne Grinovero Assignee: Manik Surtani Fix For: 5.1.0.FINAL {code} private static String extractFqcn(String path, File f) { return f.getAbsolutePath().replace(path, "").replace(File.separator, ".").replace(".class", "").replaceFirst(".", ""); } {code} A problem is here - at least I think so as I've not seen any complaints; while "replace" is expecting a literal, "replaceFirst" is taking first argument as a regex pattern to match; and "." is a wildcard.. This method is a good candidate for a *unit test* but I'm not understanding what the purpose is - if someone could plase add examples of intended functionality.
