title: Intellij IDEA writes logs (using log4j) following the ConversionPattern but without going to new line
body: <p>running my selenium suite with Intellij IDEA I'm facing this issue:
  I configured correctly log4j using this properties file</p>
  
  <pre><code># Root logger option
  log4j.rootLogger=INFO, stdout
  
  # Redirect log messages to console
  log4j.appender.stdout=org.apache.log4j.ConsoleAppender
  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
  log4j.appender.stdout.layout.ConversionPattern=%d  %p  [%c{1} : %L]  -  %m%n
  </code></pre>
  
  <p>logs are following the pattern but are written ALL IN ONE LINE in this way:</p>
  
  <pre><code>2016-05-03 11:34:05,612  INFO  [CreateTicketPage : 68]  -  clicked on save button2016-05-03 11:34:05,627  INFO  [TicketDetailsViewPage : 27]  -  Ticket Details View.page.successfully.loaded2016-05-03 11:34:07,452  WARN  [AddTransactionPage : 44]  -  Add Transaction.page.successfully.loaded2016-05-03 11:33:52,032  INFO  [TestRunner : 25]  -  executing TestRunner.setup
  </code></pre>
  
  <p><strong>%n</strong> seems ignored!! but running the tests using just <strong><em>mvn clean install</em></strong> in the command line everything look perfect. any suggestion?? is this an Intellij related issue?? </p>
