[jboss-jira] [JBoss JIRA] (JBLOGGING-55) NPE in FileAppender$Helper

NPE in FileAppender$Helper -------------------------- Key: JBLOGGING-55 URL: https://issues.jboss.org/browse/JBLOGGING-55 Project: JBoss Logging Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Ondrej Zizka Assignee: David Lloyd Attachments: log4j.xml When you set the file="..." to just a file, i.e. file="foobar.log", then you get a NPE at line if (!dir.exists()) { probably because dir = new File(filename.trim()).getParentFile(); returns null. I'd expect the appender to write to a file in new File( new File(System.getProperty("user.dir")), filename.trim() ). package org.jboss.logging.appender; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.apache.log4j.helpers.LogLog; public class FileAppender$Helper { public static void makePath(String filename) { File dir; try { URL url = new URL(filename.trim()); dir = new File(url.getFile()).getParentFile(); } catch (MalformedURLException e) { dir = new File(filename.trim()).getParentFile(); } if (!dir.exists()) { boolean success = dir.mkdirs(); if (!success) LogLog.error("Failed to create directory structure: " + dir); } } }
