For some particular pdfs, it throws IndexOutOfBoundsException

[alamkanak]

Describe the bug For some particular pdfs, the PDFTextStripper.getText() throws an exception.

To reproduce Code snippet to reproduce the behavior:

// In onCreate of MainApplication.kt
PDFBoxResourceLoader.init(this)

// In a fragment
val inputStream = context.contentResolver.openInputStream(uri)
val pdDoc = PDDocument.load(inputStream)
val pdfStripper = PDFTextStripper()
val text = pdfStripper.getText(pdDoc)

PDF example HARCOURT Invisible Umpires.pdf

Expected behavior The text should be extracted correctly from the pdf.

Actual behavior By running this code, you get the following exception:
