/**
* <p>Stores runtime configuration information for application parameters that may
* vary on restarting. This implements the Singleton pattern, but through static
* methods. That is, the first time Configuration is used, the properties are
* loaded into the Singleton instance. Subsequent calls to valueFor() retrieve
* values from the Singleton. To look up a property, use
* {@link Configuration#valueFor(String)}.
* </p>
* <p> Properties may be overridden using a second properties file, or individually
* using System properties specified on the command line. To override using a
* second properties file, specify the System property xr-conf. This should be
* the location of the second file relative to the CLASSPATH, or else a file
* path, e.g.</p>
* <code>java -Dxr-conf=resources/conf/myprops.conf</code>
* <p>
* You can also place your override properties file in your user home directory,
* in </p>
* <code>${user.home}/.flyingsaucer/local.xhtmlrenderer.conf</code>
* <p> To override a property using the System properties, just re-define the
* property on the command line. e.g.</p>
* <code>java -Dxr.property-name=new_value</code>
* <p>The order in which these will be read is: default properties (bundled with
* the core, in the jar; override configuration properties; properties file in
* user.home; and system properties.</p>
* <p>You can override as many properties as you like. </p>
* <p> Note that overrides are driven by the property names in the default
* configuration file. Specifying a property name not in that file will have no
* effect--the property will not be loaded or available for lookup.
* Configuration is NOT used to control logging levels or output; see
* LogStartupConfig.</p>
* <p>
* There are convenience converstion method for all the primitive types, in
* methods like {@link #valueAsInt(String, int)}. A default must always be provided for these
* methods. The default is returned if the value is not found, or if the
* conversion from String fails. If the value is not present, or the conversion
* fails, a warning message is written to the log.</p>

*
* $Log: Configuration.java,v $
* Revision 1.24 2009/03/08 16:49:06 pdoubleya
* Catch another couple of cases where sandbox could be broken (webstart)
*
* Revision 1.23 2009/02/08 15:18:46 pdoubleya
* Support reading properties which are not in our standard config file, passed in via an override config file or via System properties. This is to support extended configuration parameters for JDK logging, e.g. appenders, formatters, etc.
*
* Revision 1.22 2008/05/30 14:48:04 pdoubleya
* Issue 243: handle case where for some reason, a JNLP launched app could not read the default configuration file. This was throwing an RE which then cause FS logging to fail. Now load hard-coded properties (ick!) if we can't read the file itself.
*
* Revision 1.21 2008/01/27 16:40:29 pdoubleya
* Issues 186 and 130: fix configuration so that logging setup does not override any current settings for JDK logging classes. Disable logging by default.
*
* Revision 1.20 2007/12/28 14:54:33 peterbrant
* Make sure resource streams are cleaned up (bug #201, patch by kaihei)
*

*
* Revision 1.14 2006/07/17 23:21:46 pdoubleya

*
* Revision 1.13 2006/07/17 22:15:59 pdoubleya
* Added loggingEnabled switch to XRLog and config file; default logging to off there and in Configuration. Fix for Issue Tracker #123.
*

* updates to get the jnlp to work without being signed
*
* Revision 1.10 2005/06/26 01:02:22 tobega
* Now checking for SecurityException on System.getProperty
*
* Revision 1.9 2005/04/07 16:14:28 pdoubleya
* Updated to clarify relationship between Configuration and XRLog on load; Configuration must load first, but holds off on logging until XRLog is initialized. LogStartupConfig no longer used.
*
* Revision 1.8 2005/01/29 20:22:24 pdoubleya
* Clean/reformat code. Removed commented blocks, checked copyright.
*
* Revision 1.7 2004/10/23 14:06:56 pdoubleya
* Re-formatted using JavaStyle tool.
* Cleaned imports to resolve wildcards except for common packages (java.io, java.util, etc).
* Added CVS log comments at bottom.

* Revision 1.5 2004/10/18 12:10:50 pdoubleya
* Added keysByPrefix(); local override file now read from user home directory; all logging now written to console instead of Logger because of Logger setup dependency issues (logger config depends on Configuration).

* Added conversion methods for primitive datatypes, and testing in main().
*
* Revision 1.3 2004/10/14 12:55:28 pdoubleya
* Use plumbing.init logging hierarchy instead of plumbing.config.

* Revision 1.2 2004/10/14 11:12:05 pdoubleya
* Value for is now static, going against Singleton instance. Created separate logger/handler for Configuration use only, and there is a single Logger. Loggers now use INFO, FINER, FINEST for logging progess in loading configuration. Updated comments.
*
* Revision 1.1 2004/10/13 23:00:31 pdoubleya
* Added to CVS.
