Try this:
AcroFields form = stamper.getAcroFields();
PdfDictionary dict = form.getFieldItem("myTextField").getMerged(0);
PdfNumber fieldflags = dict.getAsNumber(PdfName.FF);
int flags = fieldflags.intValue();
if ((flags & PdfFormField.FF_MULTILINE) != 0)
System.out.println("Multiline!");
The code wasn't tested, I wrote it more or less from memory.
Let me know if it works; if not, I'll have to write an example.
