After upgrading our OSS Sonatype Nexus to 3.21.2 (previously on 3.18.2), the HTML View of our maven release repository is returning a HTTP 500 error.
nexus.log shows a NullPointerException Java stack trace :
Full log in attachment.
This happens at the root path of the repository. Browsing other subdirectories seems to work fine.
I suspect that an empty "folder" located at the root of the repository and named D:\archives\SVN\mimosa\mimosa_c++\v6 might be responsible of the issue.
I have not been able to delete this folder using the UI and the delete folder button.
