IndexOutOfBounds when encoding a PDF417

See original GitHub issue

I’m trying to encode a PDF417 and whenever I set the PDF417_COMPACTION to Compaction.TEXT I get this crash:

    java.lang.ArrayIndexOutOfBoundsException: length=128; index=8226
        at com.google.zxing.pdf417.encoder.PDF417HighLevelEncoder.isMixed(PDF417HighLevelEncoder.java:456)
        at com.google.zxing.pdf417.encoder.PDF417HighLevelEncoder.encodeText(PDF417HighLevelEncoder.java:298)

        at com.google.zxing.pdf417.PDF417Writer.encode(PDF417Writer.java:87)
        at com.google.zxing.MultiFormatWriter.encode(MultiFormatWriter.java:102)

Here is the code for how I am trying to create the barcode:

        var hints: MutableMap<EncodeHintType, Any>?
        
        hints = EnumMap<EncodeHintType, Any>(EncodeHintType::class.java)
        
        hints[EncodeHintType.CHARACTER_SET] = "UTF-8" 
        hints[EncodeHintType.ERROR_CORRECTION] = 6
        hints[EncodeHintType.PDF417_COMPACTION] = Compaction.TEXT
        
        val writer = MultiFormatWriter()
        val result: BitMatrix
        try {
            result = writer.encode(contents, format, img_width, img_height, hints)
        } catch (iae: WriterException) {
            // Unsupported format
            return null
        }

Is this a bug or am i doing something wrong?

I suspect it’s a bug, and I unfortunately have no idea what. I think there are a few latent bugs in the PDF417 parts. If you figure it out, feel free to open a PR. What language is this BTW?
