      Confluence is throwing this error message in the logs:

      2015-06-11 08:24:18,444 WARN [Indexer: 4] [apache.pdfbox.cos.COSDocument] getObjectsByType java.lang.ClassCastException: org.apache.pdfbox.cos.COSString cannot be cast to org.apache.pdfbox.cos.COSName

      and It seems to be throwing an out of memory for the indexer due to this bug as well:

      This is caused by a bug in the PDFBOX stated here: https://issues.apache.org/jira/browse/PDFBOX-1756

      Confluence 5.7.3, 5.8.2 and 5.8.4 ships the version 1.8.4 of pdfbox, which is affected by the bug.

      Workaround

      1) Disable the indexing of PDF attachments using this guide
      OR
      2) Update the pdfbox plugin manually in Confluence_install\confluence\WEB-INF\lib folder by replacing the original pdf plugin with a version 1.8.6 or newer. Download the newer version here

            After updating pdfbox libs with latest version 1.8.9 confluence still crashes but now with only one message:
            java.lang.OutOfMemoryError: Metaspace
