+/**
+ * Allows you to instantiate and register one or several MBeans in the MBean server
+ * coming from a remote URL. M-let is a shortcut for management applet. The m-let service does this
+ * by loading an m-let text file, which specifies information on the MBeans to be obtained.
+ * The information on each MBean is specified in a single instance of a tag, called the MLET tag.
+ * The location of the m-let text file is specified by a URL.
+ * <p>
+ * The <CODE>MLET</CODE> tag has the following syntax:
+ * <p>
+ * <<CODE>MLET</CODE><BR>
+ * <CODE>CODE = </CODE><VAR>class</VAR><CODE> | OBJECT = </CODE><VAR>serfile</VAR><BR>
+ * <CODE>ARCHIVE = "</CODE><VAR>archiveList</VAR><CODE>"</CODE><BR>
+ * <CODE>[CODEBASE = </CODE><VAR>codebaseURL</VAR><CODE>]</CODE><BR>
+ * <CODE>[NAME = </CODE><VAR>mbeanname</VAR><CODE>]</CODE><BR>
+ * <CODE>[VERSION = </CODE><VAR>version</VAR><CODE>]</CODE><BR>
+ * ><BR>
+ * <CODE>[</CODE><VAR>arglist</VAR><CODE>]</CODE><BR>
+ * <<CODE>/MLET</CODE>>
+ * <p>
+ * where:
+ * <DL>
+ * <DT><CODE>CODE = </CODE><VAR>class</VAR></DT>
+ * <DD>
+ * This attribute specifies the full Java class name, including package name, of the MBean to be obtained.
+ * The compiled <CODE>.class</CODE> file of the MBean must be contained in one of the <CODE>.jar</CODE> files specified by the <CODE>ARCHIVE</CODE>
+ * attribute. Either <CODE>CODE</CODE> or <CODE>OBJECT</CODE> must be present.
+ * </DD>
+ * <DT><CODE>OBJECT = </CODE><VAR>serfile</VAR></DT>
+ * <DD>
+ * This attribute specifies the <CODE>.ser</CODE> file that contains a serialized representation of the MBean to be obtained.
+ * This file must be contained in one of the <CODE>.jar</CODE> files specified by the <CODE>ARCHIVE</CODE> attribute. If the <CODE>.jar</CODE> file contains a directory hierarchy, specify the path of the file within this hierarchy. Otherwise a match will not be found. Either <CODE>CODE</CODE> or <CODE>OBJECT</CODE> must be present.
+ * </DD>
+ * <DT><CODE>ARCHIVE = "</CODE><VAR>archiveList</VAR><CODE>"</CODE></DT>
+ * <DD>
+ * This mandatory attribute specifies one or more <CODE>.jar</CODE> files
+ * containing MBeans or other resources used by
+ * the MBean to be obtained. One of the <CODE>.jar</CODE> files must contain the file specified by the <CODE>CODE</CODE> or <CODE>OBJECT</CODE> attribute.
+ * If archivelist contains more than one file:
+ * <UL>
+ * <LI>Each file must be separated from the one that follows it by a comma (,).
+ * <LI><VAR>archivelist</VAR> must be enclosed in double quote marks.
+ * </UL>
+ * All <CODE>.jar</CODE> files in <VAR>archivelist</VAR> must be stored in the directory specified by the code base URL.
+ * </DD>
+ * <DT><CODE>CODEBASE = </CODE><VAR>codebaseURL</VAR></DT>
+ * <DD>
+ * This optional attribute specifies the code base URL of the MBean to be obtained. It identifies the directory that contains
+ * the <CODE>.jar</CODE> files specified by the <CODE>ARCHIVE</CODE> attribute. Specify this attribute only if the <CODE>.jar</CODE> files are not in the same
+ * directory as the m-let text file. If this attribute is not specified, the base URL of the m-let text file is used.
+ * </DD>
+ * <DT><CODE>NAME = </CODE><VAR>mbeanname</VAR></DT>
+ * <DD>
+ * This optional attribute specifies the object name to be assigned to the
+ * MBean instance when the m-let service registers it. If
+ * <VAR>mbeanname</VAR> starts with the colon character (:), the domain
+ * part of the object name is the default domain of the MBean server,
+ * as returned by {@link javax.management.MBeanServer#getDefaultDomain()}.
+ * </DD>
+ * <DT><CODE>VERSION = </CODE><VAR>version</VAR></DT>
+ * <DD>
+ * This optional attribute specifies the version number of the MBean and
+ * associated <CODE>.jar</CODE> files to be obtained. This version number can
+ * be used to specify that the <CODE>.jar</CODE> files are loaded from the
+ * server to update those stored locally in the cache the next time the m-let
+ * text file is loaded. <VAR>version</VAR> must be a series of non-negative
+ * decimal integers each separated by a period from the one that precedes it.
+ * </DD>
+ * <DT><VAR>arglist</VAR></DT>
+ * <DD>
+ * This optional attribute specifies a list of one or more parameters for the
+ * MBean to be instantiated. This list describes the parameters to be passed the MBean's constructor.
+ * Use the following syntax to specify each item in
+ * <VAR>arglist</VAR>:
+ * <DL>
+ * <DT><<CODE>ARG TYPE=</CODE><VAR>argumentType</VAR> <CODE>VALUE=</CODE><VAR>value</VAR>></DT>
+ * <DD>where:
+ * <UL>
+ * <LI><VAR>argumentType</VAR> is the type of the argument that will be passed as parameter to the MBean's constructor.</UL>
+ * </DD>
+ * </DL>
+ * <P>The arguments' type in the argument list should be a Java primitive type or a Java basic type
+ * (<CODE>java.lang.Boolean, java.lang.Byte, java.lang.Short, java.lang.Long, java.lang.Integer, java.lang.Float, java.lang.Double, java.lang.String</CODE>).
+ * </DD>
+ * </DL>
+ *
+ * When an m-let text file is loaded, an
+ * instance of each MBean specified in the file is created and registered.
+ * <P>
+ * The m-let service extends the <CODE>java.net.URLClassLoader</CODE> and can be used to load remote classes
+ * and jar files in the VM of the agent.
