Description

When filling the first PDTextField in a form the performance is slow. All other PDTextFields in the form are handled quickly.

This code

PDTextField field = (PDTextField) doc.getDocumentCatalog().getAcroForm().getField("Textfield01");
long start = System.nanoTime();
field.setValue("ABCD");
long end = System.nanoTime();
double difference = (end - start)/1e6;
System.out.println(difference);

field = (PDTextField) doc.getDocumentCatalog().getAcroForm().getField("Textfield02");
start = System.nanoTime();
field.setValue("ABCD");
end = System.nanoTime();
difference = (end - start)/1e6;
System.out.println(difference);

produces the following output

9713.38
3.904
