I see that this issue had to be addressed in 21.5
PDFNET-49428 Replacing text using regular expressions causes wrapping and formatting issues
However, in 21.7 I have similar problem even literal value is used (check this thread Null Pointer Exception during setText )

I request you to try setting TextReplaceOptions with following code and share your feedback.
Document document = new Document(dataDir + "Sample_pure.pdf");
String pattern = "[+]?\\d{0,3}[ ]?\\d{10}|[+]?\\d{0,3}[ ]?(?:\\d{3}-){2}\\d{4}|[+]?\\d{0,3}[ ]?(\\d{3})[ ]?\\d{3}-?\\d{4}";
String replace = "322-233-322333335547789";
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(pattern , new TextSearchOptions(true));
TextReplaceOptions options = new TextReplaceOptions();
options.setReplaceAdjustmentAction(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);
textFragmentAbsorber.setTextReplaceOptions(options);
document.getPages().accept(textFragmentAbsorber);
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();
for (TextFragment textFragment : textFragmentCollection)
{
try
{
textFragment.setText(replace);
}
catch (Exception e) { //TODO: remove this catch once the library is fixed - there is weird NPE Log.a(PdfDocumentReplace.class).error(e);
}
textFragment.getTextState().setBackgroundColor(Color.getYellow());
}
document.save(dataDir + "Sample_pure_replace-options.pdf");It works with replacement string you provided. But with more real it does not. See attached.

I request you to try using ReplaceAdjustment.AdjustSpaceWidth instead of WholeWordsHyphenation and share your feedback.

That works and text does not collide, but consequent match is not replaced. See atached.aspose-second-part.PNG (21.4 KB)
