Adjust Logging level for apache commons logging?

In case you have no time to figure out which Logging implementation is used underneath by the Apache commons-logging, try to disable all that are in you classpath. Following code tests three implementations.

If any of the lines doesn't compile, do not add the dependency! Just remove the line.

String[] loggers = { "org.apache.pdfbox.util.PDFStreamEngine",
    "org.apache.pdfbox.pdmodel.font.PDSimpleFont", "httpclient.wire.header" , "httpclient.wire.content"
for (String ln : names) {
  // Try java.util.logging as backend
  java.util.logging.Logger.getLogger(ln).setLevel(java.util.logging.Level.WARNING);

  // Try Log4J as backend
  org.apache.log4j.Logger.getLogger(ln).setLevel(org.apache.log4j.Level.WARN);

  // Try another backend
  Log4JLoggerFactory.getInstance().getLogger(ln).setLevel(java.util.logging.Level.WARNING);
 }
