When upgrading Aspose.Words JAVA from 18.8 to 18.11, we observe a change of behaviour that the paper size of the resulted PDF has changed.
Version 18.8 > PDF page size = A4 (8.27 x 11.69 in)
Version 18.11 > PDF page size = Letter (8.50 x 11.00 in)
Can you please confirm if the default paper size has been changed from A4 to Letter? If it is true, I cannot find it in any of the release notes for version 18.9, 18.10 and 18.11.
