Hi,
I hope I'm not wrong on this, but if the second element is true
(glyphIdToCharacterCode == null) then the third one wouldn't be
evaluated, because there's no need. (short circuit evaluation)
Look at https://issues.apache.org/jira/browse/PDFBOX-5465 , the stack
trace looks just like yours.
Could it be you're not really using 2.0.28 but 2.0.26 or earlier?

Hello,
we are using pdfbox version 2.0.28 (awesome library, thanks for that!)
and recently we observed an issue (attached txt). Unfortunately I do
not have the pdf (as this issue happens before the document was saved,
so we do not have the document). However looking at the
CmapSubtable.java even in the latest code (as well as 2.0.28 version),
it seems like the condition is not safe:
private int getCharCode(int gid)
{
if (gid < 0 || glyphIdToCharacterCode == null || gid >=
glyphIdToCharacterCode.length)
{
return -1;
}
return glyphIdToCharacterCode[gid];
}
Exception and the code as well suggests that even if the
glyphIdToCharacterCode is null, it's still possible that
glyphIdToCharacerCode.length gets evaluated. What do you think please?
Best Regards,
Michal Stefan
