We appreciate issues as very valuable contributions, but just to make sure here are things that are important to do before filing an issue:

  • Only report issues (and perhaps request new features, FEATURE):,Usage Questions should be asked on Jackson-users list -- you are more likely to get help that way (and we will promptly close questions-as-issues)
  • Check to see if this issue has already been reported (quick glance at existing issues): no deep search necessary, just quick sanity check
  • Include version information for Jackson version you use
  • (optional but highly recommended) Verify that the problem occurs with the latest patch of same minor version; and even better, if possible, try using the latest stable patch version
    • For example: if you observe an issue with version 2.4.1, first upgrade to 2.4.6 to ensure problem has not already been fixed.
