****************************************************************************
Allows a uniform interface to file debug and exception information in a uniform format. Debug supports different levels/states of filing debug information (in the ascending order): OFF, ERROR, WARNING, MESSAGE and ON. A given debug level/state is enabled if the debug state/level is set to at least that state/level. For example, if the debug state is ERROR, only errors will be filed. If the debug state is WARNING, only errors and warnings will be filed. If the debug state is MESSAGE, everything will be filed. MESSAGE and ON are of the same levels; the difference between them being MESSAGE writes to a file, whereas ON writes to System.out.

Debug service uses the property file, AMConfig.properties, to set the default debug level and the output directory where the debug files will be placed. The properties file is located (using ResourceBundle semantics) from one of the directories in the CLASSPATH.

The following keys are used to configure the Debug service. Possible values for the key 'com.iplanet.services.debug.level' are: off | error | warning | message. The key 'com.iplanet.services.debug.directory' specifies the output directory where the debug files will be created. Optionally, the key 'com.sun.identity.util.debug.provider' may be used to plugin a non-default implementation of the debug service where necessary.
```
  com.iplanet.services.debug.level
  com.iplanet.services.debug.directory
  com.sun.identity.util.debug.provider
 
```
If there is an error reading or loading the properties, Debug service will redirect all debug information to System.out
If these properties are changed, the server must be restarted for the changes to take effect.

NOTE: Debugging is an IO intensive operation and may hurt application performance when abused. Particularly, note that Java evaluates the arguments to message() and warning() even when debugging is turned off. It is recommended that the debug state be checked before invoking any message() or warning() methods to avoid unnecessary argument evaluation and to maximize application performance.

  - message
```
public void message(String msg)
```
    Deprecated.
    
    Prints messages only when the debug state is either Debug.MESSAGE or Debug.ON.
    
    NOTE: Debugging is an IO intensive operation and may hurt application performance when abused. Particularly, note that Java evaluates arguments to message() even when debugging is turned off. So when the argument to this method involves the String concatenation operator '+' or any other method invocation, messageEnabled MUST be used. It is recommended that the debug state be checked by invoking messageEnabled() before invoking any message() methods to avoid unnecessary argument evaluation and maximize application performance.
    
    Parameters:
    
    msg - debug message.
    
    See Also:
    
    message(String, Throwable)
  - message
```
public void message(String msg,
                    Throwable t)
```
    Deprecated.
    
    Prints debug and exception messages only when the debug state is either Debug.MESSAGE or Debug.ON. If the debug file is not accessible and debugging is enabled, the message along with a time stamp and thread info will be printed on System.out.
    
    This method creates the debug file if does not exist; otherwise it starts appending to the existing debug file. When invoked for the first time on this object, the method writes a line delimiter of '*'s.
    
    Note that the debug file will remain open until destroy() is invoked. To conserve file resources, you should invoke destroy() explicitly rather than wait for the garbage collector to clean up.
    
    NOTE: Debugging is an IO intensive operation and may hurt application performance when abused. Particularly, note that Java evaluates arguments to message() even when debugging is turned off. It is recommended that the debug state be checked by invoking messageEnabled() before invoking any message() methods to avoid unnecessary argument evaluation and to maximize application performance.
    
    Parameters:
    
    msg - message to be printed. A newline will be appended to the message before printing either to System.out or to the debug file. If msg is null, it is ignored.
    
    t - Throwable, on which printStackTrace will be invoked to print the stack trace. If t is null, it is ignored.

    error(String, Throwable)
  - message
```
public void message(String msg,
                    Object... params)
```
    Deprecated.
    
    A convenience method for message debug statements. The message will only be formatted if the debug level is greater than WARNING, and then it will be formatted using the MessageFormatter class. The relevant message method is then called depending on whether the last parameter is an instance of Throwable.
    
    This method is convenient way of issuing warning level debug statements without having to guard the call with a check to messageEnabled(), as that check is done before evaluating the method parameters.
    
    For this optimisation to work properly, this method should not be called using string concatenation. If concatenation is required, it can be achieved using format patterns.
    
    In this way, the only cost to execution is the assembly of the varargs parameter.
    
    Parameters:
    
    msg - The debug message format, using MessageFormatter style format patterns.
    
    params - The parameters to the message, optionally with a Throwable as the last parameter.
