             Summary: PDFTextStripper runs out of memory in 2.0.28 but not in 
2.0.27 same code
                 Key: PDFBOX-5606
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5606
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.28
            Reporter: Joe Li
         Attachments: pdfbox-2.0.27.png, pdfbox-2.0.28.png

Given the follwing simplified Groovy code (for succinctness over Java)



 
{code:java}
// Groovy 4.0.12
import org.apache.pdfbox.pdmodel.PDDocument
import org.apache.pdfbox.pdmodel.PDPage
import org.apache.pdfbox.text.PDFTextStripperByArea
import java.awt.geom.Rectangle2D

int GRID_WIDTH = 10
int GRID_HEIGHT = 10

PDDocument.load(new File('./test.pdf')).withCloseable { doc ->
    doc.pages.eachWithIndex { PDPage page, int pageIndex ->
        int rows = Math.ceil((page.mediaBox.height as int) /GRID_HEIGHT)
        int columns = Math.ceil((page.mediaBox.width as int) /GRID_WIDTH)
        println "processing page $pageIndex, rows = $rows, columns = $columns"
        def rectangles = [:]
        (0..<rows).each {rowIndex ->
            (0..<columns).each { colIndex ->
                rectangles["${rowIndex * columns + colIndex}"] = new 
Rectangle2D.Float(colIndex * GRID_WIDTH, rowIndex * GRID_HEIGHT, GRID_WIDTH, 
GRID_HEIGHT)
            }
        }
        rectangles.each { key, rect ->
            PDFTextStripperByArea textStripper = new PDFTextStripperByArea()
            textStripper.addRegion(key, rect)
            textStripper.extractRegions(page)
        }
    }
}{code}
 

 

PDFBox version 2.0.28 uses ever increasing memory, but version 2.0.27 does not. 

The test.pdf file I am using can be downloaded from Apple SEC filings page, 
`8-K` from [here |[https://investor.apple.com/sec-filings/default.aspx],] but 
any 10+ page pdf with a lot of text will work. 

I have attached profiler screenshots of the difference. 

Thanks in advance for your help.
