 * Thrown on accessing indices in dumb mode. Possible fixes:
 * <li> if {@link com.intellij.openapi.actionSystem.AnAction#actionPerformed(com.intellij.openapi.actionSystem.AnActionEvent)} is in stack trace,
 * consider making the action not implement {@link com.intellij.openapi.project.DumbAware}.
 * <li> if this access is performed from some invokeLater activity, consider replacing it with
 * {@link com.intellij.openapi.project.DumbService#smartInvokeLater(Runnable)}
 * <li> otherwise, add {@link DumbService#isDumb()} checks where necessary
