Someone may want to cc the submitter of this port (yahoo.fr:macosx12345).

There are a couple of (closed) upstream tickets that this resembles: ​https://gitlab.com/pdftk-java/pdftk/issues/2 ​https://gitlab.com/pdftk-java/pdftk/issues/7

It also appears that in the future this port may need to use Apache commons-text, since that is where StringEscapeUtils has moved to; not sure if the upstream project is aware of this.

I've reported it to them here: ​https://gitlab.com/pdftk-java/pdftk/-/issues/51

pdftk-java: Update to 3.1.1 and fix class path

Closes: #58905

[ryandesign (Ryan Carsten Schmidt)]

I think that fixes it but I should add that I'm almost completely unfamiliar with Java so it's possible I did something wrong in creating the commons-text port (I modeled it on the commons-lang3 port) or in fixing the class path issues in pdftk-java. If so, please file more tickets.

pdftk-java: Don't use commons-text

Remove unnecessary commons-text dependency and the source patch to use
it. StringEscapeUtils may be deprecated in commons-lang3, but it's still
there. Turns out the only reason why it didn't run before was that we
weren't specifying the class path.
