+/**
+ * A simple service-provider lookup mechanism. A <i>service</i> is a
+ * well-known set of interfaces and (usually abstract) classes. A <i>service
+ * provider</i> is a specific implementation of a service. The classes in a
+ * provider typically implement the interfaces and subclass the classes defined
+ * in the service itself. Service providers may be installed in an
+ * implementation of the Java platform in the form of extensions, that is, jar
+ * files placed into any of the usual extension directories. Providers may
+ * also be made available by adding them to the applet or application class
+ * path or by some other platform-specific means.
+ *
+ * <p> In this lookup mechanism a service is represented by an interface or an
+ * abstract class. (A concrete class may be used, but this is not
+ * recommended.) A provider of a given service contains one or more concrete
+ * classes that extend this <i>service class</i> with data and code specific to
+ * the provider. This <i>provider class</i> will typically not be the entire
+ * provider itself but rather a proxy that contains enough information to
+ * decide whether the provider is able to satisfy a particular request together
+ * with code that can create the actual provider on demand. The details of
+ * provider classes tend to be highly service-specific; no single class or
+ * interface could possibly unify them, so no such class has been defined. The
+ * only requirement enforced here is that provider classes must have a
+ * zero-argument constructor so that they may be instantiated during lookup.
+ *
+ * <p> A service provider identifies itself by placing a provider-configuration
+ * file in the resource directory <tt>META-INF/services</tt>. The file's name
+ * should consist of the fully-qualified name of the abstract service class.
+ * The file should contain a list of fully-qualified concrete provider-class
+ * names, one per line. Space and tab characters surrounding each name, as
+ * well as blank lines, are ignored. The comment character is <tt>'#'</tt>
+ * (<tt>0x23</tt>); on each line all characters following the first comment
+ * character are ignored. The file must be encoded in UTF-8.
+ *
+ * <p> If a particular concrete provider class is named in more than one
+ * configuration file, or is named in the same configuration file more than
+ * once, then the duplicates will be ignored. The configuration file naming a
+ * particular provider need not be in the same jar file or other distribution
+ * unit as the provider itself. The provider must be accessible from the same
+ * class loader that was initially queried to locate the configuration file;
+ * note that this is not necessarily the class loader that found the file.
+ *
+ * <p> <b>Example:</b> Suppose we have a service class named
+ * <tt>java.io.spi.CharCodec</tt>. It has two abstract methods:
+ *
+ * <pre>
+ * public abstract CharEncoder getEncoder(String encodingName);
+ * public abstract CharDecoder getDecoder(String encodingName);
+ * </pre>
+ *
+ * Each method returns an appropriate object or <tt>null</tt> if it cannot
+ * translate the given encoding. Typical <tt>CharCodec</tt> providers will
+ * support more than one encoding.
+ *
+ * <p> If <tt>sun.io.StandardCodec</tt> is a provider of the <tt>CharCodec</tt>
+ * service then its jar file would contain the file
+ * <tt>META-INF/services/java.io.spi.CharCodec</tt>. This file would contain
+ * the single line:
+ *
+ * <pre>
+ * sun.io.StandardCodec # Standard codecs for the platform
+ * </pre>
+ *
+ * To locate an encoder for a given encoding name, the internal I/O code would
+ * do something like this:
+ *
+ * <pre>
+ * CharEncoder getEncoder(String encodingName) {
+ * Iterator ps = Service.providers(CharCodec.class);
+ * while (ps.hasNext()) {
+ * CharCodec cc = (CharCodec)ps.next();
+ * CharEncoder ce = cc.getEncoder(encodingName);
+ * if (ce != null)
+ * return ce;
+ * }
+ * return null;
+ * }
+ * </pre>
+ *
+ * The provider-lookup mechanism always executes in the security context of the
+ * caller. Trusted system code should typically invoke the methods in this
+ * class from within a privileged security context.
