Bug 173902 remove EXPERIMENTAL markings from 3.3 IDE Undo API
Need to remove the EXPERIMENTAL javadoc from the new API I introduced in 3.3. See org.eclipse.ui.ide.undo org.eclipse.jface.fieldassist
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/ide/undo/AbstractWorkspaceOperation.java

	public boolean canRedo() {
		return isValid();
	}
	/**
	 * Execute the specified operation. This implementation executes the
	 * operation in a workspace runnable and catches any CoreExceptions
	 * resulting from the operation. Unhandled CoreExceptions are propagated as
	 * ExecutionExceptions.

	 *            the progress monitor to use for the operation
	 * @param uiInfo
	 *            the IAdaptable (or <code>null</code>) provided by the
	 *            caller in order to supply UI information for prompting the
	 *            user if necessary. When this parameter is not
	 *            <code>null</code>, it contains an adapter for the

	 *         to <code>OK</code> if the operation was successful, and
	 *         <code>ERROR</code> if it was not. Any other status is assumed
	 *         to represent an incompletion of the execution.
	 * @throws ExecutionException
	 *             if an exception occurred during execution.
