      Summary

      The error we're seeing in Synchrony is a core dump with

      V  [libjvm.so+0xd6f768]  Unsafe_GetInt+0x174

      We're affected by this bug in a library called lz4 for sparcv9 hardware which is fixed, but not in the latest release 1.3.

      The change went from checking the OS is Solaris to Solaris and SunOS which is what you're machine is reporting. The code change included going from

      src/java/net/jpountz/util/Native.java
      } else if (osName.contains("Solaris")) {

      to

      src/java/net/jpountz/util/Native.java
      } else if (osName.contains("Solaris") || osName.contains("SunOS")) {

      plus some other bits.

      So, the library lz4 1.3 is used by a library we use called nippy 2.12.0.

      And nippy 2.12.0 is used in a library called faraday 1.9.0.

      And we use Faraday.

      Synchrony in Confluence Sever doesn't need Faraday. It's a hangover from the Cloud version of Synchrony that we haven't removed.

      Environment

      • sparcv9 hardware
      • OS reported as SunOS

      Expected Results

      It works.

      Workaround

      None

      Notes

      Although Solaris is not a supported platform, many enterprises use it, and this issue is using a library that we don't use in serverland.

      This is here to track
