Hello, in pdfbox 3.0.0-alpha3 I am encountering the following error:
java.lang.NullPointerException: Cannot read the array length because
"this.glyphIdToCharacterCode" is null
org.apache.fontbox.ttf.CmapSubtable.getCharCode(CmapSubtable.java:638)
org.apache.fontbox.ttf.CmapSubtable.getCharCodes(CmapSubtable.java:655)
org.apache.pdfbox.pdmodel.font.PDType0Font.toUnicode(PDType0Font.java:546)...
This is thrown by the following code :
while (currentPosition < bytes.size && currentCharacterBytes++ <
maxEncodingBytes) {
potentialCode =
potentialCode.shl(8).or(bytes[currentPosition++].toInt().and(0xFF))
val potentialRepresentation: String
potentialRepresentation = font.toUnicode(potentialCode) ?: continue //
Exception is thrown here
unicodeRepresentation.append(potentialRepresentation)
codes.add(potentialCode)
currentCharacterBytes = 0
potentialCode = 0
}
Unfortunately, the pdf that caused this is not available, this error was
discovered in review of the logs. Attempts to recreate the exception by
creating a pdf through pdfbox and manually using different glyphs/fonts/emoji
combinations were unsuccessful. From the exception itself, it would seem that
the glyphIdToCharacterCode array in CmapSubtable is not being initialized.
