Michael Klink commented on PDFBOX-5099:
---------------------------------------
{quote}I guess it is an illegal Date value .{quote}
Yes, it is. According to the specification:
{panel:title=ISO 32000-2:2017, section 7.9.4 Dates}
date shall be a text string containing no whitespace, of the form:
(D:YYYYMMDDHHmmSSOHH'mm)
...
The prefix D: shall be present, the year field (YYYY) shall be present and all
other fields may be present but only if all of their preceding fields are also
present. The APOSTROPHE following the hour offset field (HH) shall only be
present if the HH field is present. The minute offset field (mm) shall only be
present if the APOSTROPHE following the hour offset field (HH) is present.
{panel}
So {{(D: )}} is wrong in two ways, the year YYYY is missing and there is an
invalid space.
