Description
Hi,
there was a NPE in getCharCode method of CmapSubtable:
java.lang.NullPointerException: Cannot read the array length because "this.glyphIdToCharacterCode" is null at org.apache.fontbox.ttf.CmapSubtable.getCharCode(CmapSubtable.java:669) at org.apache.fontbox.ttf.CmapSubtable.getCharCodes(CmapSubtable.java:686) at org.apache.pdfbox.pdmodel.font.PDType0Font.toUnicode(PDType0Font.java:533) at org.apache.pdfbox.contentstream.PDFStreamEngine.showGlyph(PDFStreamEngine.java:838) at org.apache.pdfbox.contentstream.PDFStreamEngine.showText(PDFStreamEngine.java:776) at org.apache.pdfbox.contentstream.PDFStreamEngine.showTextStrings(PDFStreamEngine.java:681) at org.apache.pdfbox.contentstream.operator.text.ShowTextAdjusted.process(ShowTextAdjusted.java:53) at org.apache.pdfbox.contentstream.PDFStreamEngine.processOperator(PDFStreamEngine.java:966) at org.apache.pdfbox.contentstream.PDFStreamEngine.processStreamOperators(PDFStreamEngine.java:541) at org.apache.pdfbox.contentstream.PDFStreamEngine.processStream(PDFStreamEngine.java:516) at org.apache.pdfbox.contentstream.PDFStreamEngine.processPage(PDFStreamEngine.java:155) at org.apache.pdfbox.text.LegacyPDFStreamEngine.processPage(LegacyPDFStreamEngine.java:155) at org.apache.pdfbox.text.PDFTextStripper.processPage(PDFTextStripper.java:363) at org.apache.pdfbox.text.PDFTextStripper.processPages(PDFTextStripper.java:291) at org.apache.pdfbox.text.PDFTextStripper.writeText(PDFTextStripper.java:238) at org.apache.pdfbox.text.PDFTextStripper.getText(PDFTextStripper.java:202)
Unfortunately I cannot provide pdf for privacy reason (and I don't have it anyway), Looking at the code, it suggests that even if the glyphIdToCharacterCode is null, it's still possible that glyphIdToCharacerCode.length gets evaluated
