Tilman Hausherr commented on PDFBOX-1692:
-----------------------------------------
There's a problem with the EOF handling in CMapParser.java. In
parseNextToken(), at "case -1", the -1 is returned and no exception is thrown.
In parse(), at line 217 there's a loop from startCode to endCode. For the
"problem" file, startCode is 0 0 and endCode is 255 255, so the loop will be
run 65536 times. And even that will happen many times, until memory is out.
Even throwing an exception doesn't help (I tried, but parse() is called again).
