John Aylward resolved PDFBOX-3260.
----------------------------------
    Resolution: Not A Problem

I can't seem to reproduce it in test cases outside of Tomcat either. It is likely some kind of configuration issue on my end. For reference, here is the test case I used to match the resource load that is happening in tomcat:

The actual resource in my configuration is in a JAR on the tomcat classpath, so I tried replicating that here.

{code:title=Test.java|borderStyle=solid}
@Test
public void testFontFromJar() throws IOException {
    final URL jar = this.getClass().getResource("/micrFontInJar.jar");

    assert jar != null : "Unable to locate TTF Jar in classpath";

    URL ttfURL = new URL("jar:" + jar.toString() + "!/MICREncoding.ttf");

    try (PDDocument pdf = new PDDocument();//
            final InputStream fontStream = ttfURL.openStream()) {
        assert fontStream != null : "Unable to locate font resource";
        final PDType0Font micrFont = PDType0Font.load(pdf, fontStream);
        assert micrFont != null : "Unable to load MICR font";
    }

    ttfURL = new URL("jar:" + jar.toString() + "!/micrenc.ttf");

    try (PDDocument pdf = new PDDocument();//
            final InputStream fontStream = ttfURL.openStream()) {
        assert fontStream != null : "Unable to locate font resource";
        final PDType0Font micrFont = PDType0Font.load(pdf, fontStream);
        assert micrFont != null : "Unable to load MICR font";
    }

}
{code}

The tests pass for both fonts in the JAR, so I'll inspect my tomcat configuration/environment to see what could be causing the issue. Maybe I accidentally have 2 of the same files on the classpath and it's grabbing the wrong one or some other odd problem.

Thanks for the help.
