The previous one wouldn't compile because I used hyphens in my package
name. Regenerate the project structure replacing the hyphens with
underscores:
$ mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-simple -DarchetypeVersion=1.4
...
Define value for property 'groupId': com.teddywing.pdf_form_replace_font2
Define value for property 'artifactId': pdf-form-replace-font2
Define value for property 'version' 1.0-SNAPSHOT: : 0.0.1-SNAPSHOT
Define value for property 'package' com.teddywing.pdf_form_replace_font2: :

I followed the Maven Getting Started
(https://maven.apache.org/guides/getting-started/index.html) guide to
set up a project structure so I could use it to manage dependencies. I
picked the 'maven-archetype-simple' archetype
(https://maven.apache.org/archetypes/maven-archetype-simple/).
This code was generated with the following command and interactive
prompts:
$ mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-simple -DarchetypeVersion=1.4

This finally works. My guess is that the library was embedding the font
and, crucially, _subsetting_ the font. But since we don't set any values
before writing out the PDF, it was probably subsetting to 0 glyphs,
effectively making it appear that the desired font wasn't being set.
Forcing no embedding renders the font correctly.

Still working on this, trying to figure out why the font replacement
isn't working.

Don't change all of the input fields' font to the replacement, only
those with a specific font we want to replace.

Use iText to change the font of interactive form fields in a PDF.
Changes the font in 'f1040.pdf' to Courier.
This code is based on the following example from iText:

For now I just downloaded the dependencies' JAR files and put them in a
'lib/' directory rather than have to learn how to use a dependency
management tool like Maven. Here is the contents of the 'lib/'
directory:
barcodes-7.2.2.jar
commons-7.2.2.jar
font-asian-7.2.2.jar
forms-7.2.2.jar
hyph-7.2.2.jar
io-7.2.2.jar
kernel-7.2.2.jar
layout-7.2.2.jar
pdfa-7.2.2.jar
pdftest-7.2.2.jar
sign-7.2.2.jar
slf4j-api-1.7.9.jar
styled-xml-parser-7.2.2.jar
svg-7.2.2.jar
To run this:
$ make
$ make run
