Hi,
I've the same effects here and I already suspected the refactored io-code.
@Tilamn: Good to hear that you already found the culprit. Do you already have
a fix or should I have a look as well?
I don't have a fix. Please have a look yourself too. I'm still kindof surprised
that this would happen overnight despite no code change. Maybe some change on
apache's own server. And the javadoc of available() reads like it's more about
astrology.

It happens in RandomAccessReadBuffer(InputStream input) .
input.available() returns 0 despite that more bytes are available. This can
be shown with this change:
if (remainingBytes == 0 && input.available() > 0)
{
expandBuffer();
}
else
{
////////////////////// new
int by = input.read();
if (by != -1)
{
throw new IOException("hey there was more");
}
///////////////////// end of new code
currentBuffer.limit(offset);
break;
}
also, this test code
@Test
void testBlah() throws IOException
{
System.out.println("start");
try (InputStream is = new
URL("https://issues.apache.org/jira/secure/attachment/13017227/stringwidth.pdf";).openStream())
{
RandomAccessReadBuffer rarb = new RandomAccessReadBuffer(is);
System.out.println(rarb.length());
}
}
shows 8192 bytes. The real size of the file is 34KB.

Something is weird with the trunk build. It fails on my PC and on Jenkins
despite no changes.
An example is PDFontTest.testPDFox5048(). That one fails as it is, but
doesn't fail when using a local file.
Also, the URL
https://issues.apache.org/jira/secure/attachment/13017227/stringwidth.pdf
has a FontFile3 = null when loaded with CTRL-U in PDFDebugger, but not when
loaded locally.
Same test works fine when done in the 2.0 build
