Search text spanning over multiple lines

Hello,
we updated our aspose version from 16.6.0 to 17.10.

Since the update we have a problem with the following code:

  // search for text
  Document calculatorDoc = new Document(new ByteArrayInputStream(out.toByteArray()));
  TextFragmentAbsorber textAbsorber = new TextFragmentAbsorber(".*\n*");
  textAbsorber.setTextSearchOptions(new TextSearchOptions(true));
  calculatorDoc.getPages().accept(textAbsorber);
  TextFragmentCollection textFragmentCollection = textAbsorber.getTextFragments();
  textFragmentCollection.get_Item(1).getRectangle().getHeight();

We try to get the height of a single textfragment at one page. We know that there is just one fragment at the page .
Before the update it was possible to get the height of a text spanning over multiple lines.
After the update the TextAbsorber just finds the first line of the text.
How can we fix the problem?

Thanks,
Ina
