BorderPropertySet.java -- Organize imports (had compile issues without org.w3c.dom).
VerifyGlyphExists.java -- Compare line 100 (old) and line 110 (PR); the codepoint was always 0, which looks like a bug. Other updates modernize the syntax and apply IDE-recommended changes, including try-with-resources. This closes the opened font's file stream, which is technically another bug but one that would never affect the application in practice.
Changes:
org.w3c.dom
in pom.
