------------------------------------------------------------------
I tried it with jdk8, 11 and 14 without trouble and used this code:
{code:java}
public class PDFBox4859_InflateTest
{
public static void main(String[] args) throws DataFormatException,
IOException
{
String dir = "XXXXXXXXXX";
File inFile = new File(dir, "FontFile2.flatencoded");
File ttfFile = new File(dir, "flatendecoded.ttf");
try (InputStream in = new FileInputStream(inFile);
OutputStream out = new FileOutputStream(ttfFile))
{
byte[] buf = new byte[2048];
// skip zlib header
in.read();
in.read();
int read = in.read(buf);
Inflater inflater = new Inflater(true);
inflater.setInput(buf, 0, read);
byte[] res = new byte[1024];
boolean dataWritten = false;
try
{
while (true)
{
int resRead = 0;
try
{
resRead = inflater.inflate(res);
}
catch (DataFormatException exception)
{
if (dataWritten)
{
// some data could be read -> don't throw an
exception
System.err.println("FlateFilter: premature end of
stream due to a DataFormatException");
break;
}
else
{
// nothing could be read -> re-throw exception
throw exception;
}
}
if (resRead != 0)
{
out.write(res, 0, resRead);
dataWritten = true;
continue;
}
if (inflater.finished() || inflater.needsDictionary() ||
in.available() == 0)
{
break;
}
read = in.read(buf);
inflater.setInput(buf, 0, read);
}
}
finally
{
inflater.end();
}
}
TrueTypeFont ttf = new TTFParser(true).parse(ttfFile);
ttf.close();
}
}
{code}
