Multi-catch can be split into separate catch blocks

Reports multi-catch sections and suggests splitting them into separate catch blocks.

Example:

  try {
    int i = getIndex();
  } catch (NullPointerException|IndexOutOfBoundsException e) {
    e.printStackTrace();
  }

After the quick-fix is applied:

  try {
    int i = getIndex();
  } catch (NullPointerException e) {
    e.printStackTrace();
  } catch (IndexOutOfBoundsException e) {
    e.printStackTrace();
  }
