-/**
- * A custom class loader which enables the reloading
- * of classes for each test run. The class loader
- * can be configured with a list of package paths that
- * should be excluded from loading. The loading
- * of these packages is delegated to the system class
- * loader. They will be shared across test runs.
- * <p>
- * The list of excluded package paths is specified in
- * a properties file "excluded.properties" that is located in
- * the same place as the TestCaseClassLoader class.
- * <p>
- * <b>Known limitation:</b> the TestCaseClassLoader cannot load classes
- * from jar files.
- * {@hide} - Not needed for 1.0 SDK
