Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/runtime/Assert
Seems the runtime.jar has no org.eclipse.core.runtime.Assert in it:
Am I using a wrong version though it's shipped with my eclipse?
UPDATE
I don't have Plugin Development Perspective:
                You have probably not downloaded Eclipse RCP.  You probably have downloaded Eclipse for Java developers.  You can download the RCP plugins from the update manager.

                +1 for the Ctrl+Shift+T tip. The input line for the name pattern in that dialog has many useful features. You can use * and ? for filtering, or use CamelCase filtering, so entering IArE will present (possibly among others) the IllegalArgumentException. You can enter abbreviated package names like j.u.BS to get (among others) the java.util.BitSet.

                Now it's reporting Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/commands/common/EventManager

                It works in Java perspective too. Plugin devel. perspective is available in Eclipse for RCP and RAP developers as Andrew noted.
