XMLWordPrintable

      Summary

      Uploading some PPTX files to Confluence can cause OutOfMemory error while generating preview.

      Steps to Reproduce

      1. Upload a Powerpoint file with 300 pages containing graphs/pictures to Confluence (attached, 9.87MB)
      2. Open file in preview window several times

      Expected Results

      Confluence should pre-calculate the resource commitment before previewing the document. Similar to CONFSERVER-45209

      Actual Results

      Confluence became unresponsive. The below exception is thrown in the catalina.out file:
