      Root Cause

      An update to the bundled AdoptOpenJDK8u222-b10 in Confluence 6.15.8 has resulted in a library dependency issue resulting in the Synchrony process failing to start.

      Resolution

      An urgent release has been made to address this issue.

      • Please upgrade to Confluence 6.13.8 if you are on the 6.13 Enterprise Release.
      • Please upgrade to Confluence 6.15.9 if you are on the 6.15 release.

      Workaround

      Downgrade the bundled Java AdoptOpenJDK from 1.8.0_222-10 to previously bundled JVM (i.e. 1.8.0_202-b08) resolves the issue.

      Substitute C:\Program Files\Atlassian\Confluence below if you have Confluence installed in a non-default location.

      1. Download AdoptOpenJDK 8u202-b08 from https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u202-b08/OpenJDK8U-jre_x64_windows_hotspot_8u202b08.zip
      2. Shutdown Confluence
      3. Rename C:\Program Files\Atlassian\Confluence\jre to C:\Program Files\Atlassian\Confluence\jre8u222-b10
      4. Extract OpenJDK8U-jre_x64_windows_hotspot_8u202b08.zip to C:\Program Files\Atlassian\Confluence - it will extract with a sub-directory called jdk8u202-b08-jre
        • Rename the new C:\Program Files\Atlassian\Confluence\jdk8u202-b08-jre to C:\Program Files\Atlassian\Confluence\jre
      5. Start Confluence and Collaborative Editing should now start
