/**
* Initializes DLTKCore internal structures to allow subsequent operations (such as the ones that
* need a resolved classpath) to run full speed. A client may choose to call this method in a
* background thread early after the workspace has started so that the initialization is
* transparent to the user.
*
* <p>However calling this method is optional. Services will lazily perform initialization when
* invoked. This is only a way to reduce initialization overhead on user actions, if it can be
* performed before at some appropriate moment.
*
* <p>This initialization runs accross all Java projects in the workspace. Thus the workspace root
* scheduling rule is used during this operation.
*
* <p>This method may return before the initialization is complete. The initialization will then
* continue in a background thread.
*
* <p>This method can be called concurrently.
*
* @param monitor a progress monitor, or <code>null</code> if progress reporting and cancellation
* are not desired
* @exception CoreException if the initialization fails, the status of the exception indicates the
* reason of the failure
* @since 3.1
