Please, before opening a new issue look through the open or resolved ones, you may already find your problem. Also do not use the system to ask questions, for that purpose we have a mailing list. We read the list continuously. If you are unsure whether the problem is caused by a bug or your usage of XStream, use the user's list first. If we can confirm a bug, you may still open an issue. Also do not report on the list that you have created a new issue, we are already notified by the system.
If you like to contribute code, we prefer a patch/diff in contrast to the complete modified file - unless the file itself is new. Please provide also unit tests, XStream has a high test coverage and we like to keep this. Additionally, if you provide new files, please also add a header with the copyright. It must be a BSD license, simply take the header of any other file in the distribution as template. Otherwise we might not be able to add any code of you.
XStream tracks and manages its issues issues with GitHub's integrated issue management.
XStream was hosted for more than a decade at Codehaus and used Codehaus' installation of JIRA as issue management. With the help of Paul Hammant's export script we can still provide a static version of all the former issues.
