> infinite loop at org.apache.pdfbox.pdfparser.BaseParser.parseCOSHexString(BaseParser.java:1010)
> private final COSString parseCOSHexString() throws IOException
> {
> ...
>             // read till the closing bracket was found
>             do 
>             {
>                 c = pdfSource.read();
>             } while ( c != '>' );
> ...   
> if pdfSource.read() returns EOF, the loop never terminates;
> Testcase:
> PDDocument doc = PDDocument.load (new FileInputStream("..."));
> 2 real world pdf-files that cause the loop could be attached; do not know if their PDF is completely valid, but at least they are displayed via Preview in MacOSX.
