    Details

    • Subcomponent:
      2d
    • CPU:
      x86_64
    • OS:
      windows_10

      Description

      ADDITIONAL SYSTEM INFORMATION :
      Windows 10, jdk 13.0.1, also jdk8 202

      A DESCRIPTION OF THE PROBLEM :
      The attached code either never ends or throws OOM. The code is reduced from https://issues.apache.org/jira/browse/PDFBOX-4718 :
      - download PDFDebugger
        https://pdfbox.apache.org/download.cgi
        search for debugger-app-2.0.18.jar
      - run it
      - press CTRL-U for "open URL" dialog
      - enter
        https://issues.apache.org/jira/secure/attachment/12989118/example.pdf

      never ends or throws OOM

      possibly duplicate of JDK-6955969, but that one has no sample code, and does end after some time.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      run the attached code
      "C:\Program Files\Java\jdk-13.0.1\bin\java" -Xmx2g -jar PDFBox4718Intersect.jar

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      alive1
      alive2
      alive3
      ACTUAL -
      alive1
      alive2
