 class StreamGobbler
extends Thread

Provides a stream gobbler. Typical usage is to drain the error and output streams when using Runtime.exec().

   Process process = Runtime.getRuntime().exec(command);

   StreamGobbler errorGobbler = new StreamGobbler(process.getErrorStream(), "ERROR", false);
   StreamGobbler outputGobbler = new StreamGobbler(process.getInputStream(), "OUTPUT", false);

   errorGobbler.start();
   outputGobbler.start();

   try
   {
       process.waitFor();
   }
   catch (InterruptedException e)
   {
       LOGGER.log(Level.SEVERE, e.getMessage(), e);
   }
