+ * <p>
+ * This method performs the main task of constructing an framework instance
+ * and starting its execution. The following functions are performed
+ * when invoked:
+ * </p>
+ * <ol>
+ * <li><i><b>Read the system properties file.<b></i> This is a file
+ * containing properties to be pushed into <tt>System.setProperty()</tt>
+ * before starting the framework. This mechanism is mainly shorthand
+ * for people starting the framework from the command line to avoid having
+ * to specify a bunch of <tt>-D</tt> system property definitions.
+ * The only properties defined in this file that will impact the framework's
+ * behavior are the those concerning setting HTTP proxies, such as
+ * <tt>http.proxyHost</tt>, <tt>http.proxyPort</tt>, and
+ * <tt>http.proxyAuth</tt>.
+ * </li>
+ * <li><i><b>Perform system property variable substitution on system
+ * properties.</b></i> Any system properties in the system property
+ * file whose value adheres to <tt>${<system-prop-name>}</tt>
+ * syntax will have their value substituted with the appropriate
+ * system property value.
+ * </li>
+ * <li><i><b>Read the framework's configuration property file.</b></i> This is
+ * a file containing properties used to configure the framework
+ * instance and to pass configuration information into
+ * bundles installed into the framework instance. The configuration
+ * property file is called <tt>config.properties</tt> by default
+ * and is located in the same directory as the <tt>felix.jar</tt>
+ * file, which is typically in the <tt>lib/</tt> directory of the
+ * Felix installation directory. It is possible to use a different
+ * location for the property file by specifying the desired URL
+ * using the <tt>felix.config.properties</tt> system property;
+ * this should be set using the <tt>-D</tt> syntax when executing
+ * the JVM. Refer to the
+ * <a href="Felix.html#start(org.apache.felix.framework.util.MutablePropertyResolver, org.apache.felix.framework.util.MutablePropertyResolver, java.util.List)">
+ * <tt>Felix.start()</tt></a> method documentation for more
+ * information on the framework configuration options.
+ * </li>
+ * <li><i><b>Perform system property variable substitution on configuration
+ * properties.</b></i> Any configuration properties whose value adheres to
+ * <tt>${<system-prop-name>}</tt> syntax will have their value
+ * substituted with the appropriate system property value.
+ * </li>
+ * <li><i><b>Ensure the default bundle cache has sufficient information to
+ * initialize.</b></i> The default implementation of the bundle cache
+ * requires either a profile name or a profile directory in order to
+ * start. The configuration properties are checked for at least one
+ * of the <tt>felix.cache.profile</tt> or <tt>felix.cache.profiledir</tt>
+ * properties. If neither is found, the user is asked to supply a profile
+ * name that is added to the configuration property set. See the
+ * <a href="cache/DefaultBundleCache.html"><tt>DefaultBundleCache</tt></a>
+ * documentation for more details its configuration options.
+ * </li>
+ * <li><i><b>Creates and starts a framework instance.</b></i> A simple
+ * <a href="util/MutablePropertyResolver.html"><tt>MutablePropertyResolver</tt></a>
+ * is created for the configuration property file and is passed
+ * into the framework when it is started.
+ * </li>
+ * </ol>
+ * <p>
+ * It should be noted that simply starting an instance of the framework is not enough
+ * to create an interactive session with it. It is necessary to install
+ * and start bundles that provide an interactive impl; this is generally
+ * done by specifying an "auto-start" property in the framework configuration
+ * property file. If no interactive impl bundles are installed or if
+ * the configuration property file cannot be found, the framework will appear to
+ * be hung or deadlocked. This is not the case, it is executing correctly,
+ * there is just no way to interact with it. Refer to the
+ * <a href="Felix.html#start(org.apache.felix.framework.util.MutablePropertyResolver, org.apache.felix.framework.util.MutablePropertyResolver, java.util.List)">
+ * <tt>Felix.start()</tt></a> method documentation for more information on
+ * framework configuration options.
+ * </p>
+ * @param argv An array of arguments, all of which are ignored.
+ * @throws Exception If an error occurs.

- /**
- * <p>
- * This method performs the main task of constructing an framework instance
- * and starting its execution. The following functions are performed
- * when invoked:
- * </p>
- * <ol>
- * <li><i><b>Read the system properties file.<b></i> This is a file
- * containing properties to be pushed into <tt>System.setProperty()</tt>
- * before starting the framework. This mechanism is mainly shorthand
- * for people starting the framework from the command line to avoid having
- * to specify a bunch of <tt>-D</tt> system property definitions.
- * The only properties defined in this file that will impact the framework's
- * behavior are the those concerning setting HTTP proxies, such as
- * <tt>http.proxyHost</tt>, <tt>http.proxyPort</tt>, and
- * <tt>http.proxyAuth</tt>.
- * </li>
- * <li><i><b>Perform system property variable substitution on system
- * properties.</b></i> Any system properties in the system property
- * file whose value adheres to <tt>${<system-prop-name>}</tt>
- * syntax will have their value substituted with the appropriate
- * system property value.
- * </li>
- * <li><i><b>Read the framework's configuration property file.</b></i> This is
- * a file containing properties used to configure the framework
- * instance and to pass configuration information into
- * bundles installed into the framework instance. The configuration
- * property file is called <tt>config.properties</tt> by default
- * and is located in the same directory as the <tt>felix.jar</tt>
- * file, which is typically in the <tt>lib/</tt> directory of the
- * Felix installation directory. It is possible to use a different
- * location for the property file by specifying the desired URL
- * using the <tt>felix.config.properties</tt> system property;
- * this should be set using the <tt>-D</tt> syntax when executing
- * the JVM. Refer to the
- * <a href="Felix.html#start(org.apache.felix.framework.util.MutablePropertyResolver, org.apache.felix.framework.util.MutablePropertyResolver, java.util.List)">
- * <tt>Felix.start()</tt></a> method documentation for more
- * information on the framework configuration options.
- * </li>
- * <li><i><b>Perform system property variable substitution on configuration
- * properties.</b></i> Any configuration properties whose value adheres to
- * <tt>${<system-prop-name>}</tt> syntax will have their value
- * substituted with the appropriate system property value.
- * </li>
- * <li><i><b>Ensure the default bundle cache has sufficient information to
- * initialize.</b></i> The default implementation of the bundle cache
- * requires either a profile name or a profile directory in order to
- * start. The configuration properties are checked for at least one
- * of the <tt>felix.cache.profile</tt> or <tt>felix.cache.profiledir</tt>
- * properties. If neither is found, the user is asked to supply a profile
- * name that is added to the configuration property set. See the
- * <a href="cache/DefaultBundleCache.html"><tt>DefaultBundleCache</tt></a>
- * documentation for more details its configuration options.
- * </li>
- * <li><i><b>Creates and starts a framework instance.</b></i> A simple
- * <a href="util/MutablePropertyResolver.html"><tt>MutablePropertyResolver</tt></a>
- * is created for the configuration property file and is passed
- * into the framework when it is started.
- * </li>
- * </ol>
- * <p>
- * It should be noted that simply starting an instance of the framework is not enough
- * to create an interactive session with it. It is necessary to install
- * and start bundles that provide an interactive impl; this is generally
- * done by specifying an "auto-start" property in the framework configuration
- * property file. If no interactive impl bundles are installed or if
- * the configuration property file cannot be found, the framework will appear to
- * be hung or deadlocked. This is not the case, it is executing correctly,
- * there is just no way to interact with it. Refer to the
- * <a href="Felix.html#start(org.apache.felix.framework.util.MutablePropertyResolver, org.apache.felix.framework.util.MutablePropertyResolver, java.util.List)">
- * <tt>Felix.start()</tt></a> method documentation for more information on
- * framework configuration options.
- * </p>
- * @param argv An array of arguments, all of which are ignored.
- * @throws Exception If an error occurs.
