Major Some components in an npm repo will persistently throw ConcurrentModificationException on trying to delete them. This seems to affect all versions of a component with a semver-patch range (every 1.1.x version of a component may be affected but 1.2.x will not be).
Using nexus 3.0.1-01 inside a docker container loosely based off the official sonatype nexus3 dockerfile. Specifically, https://download.sonatype.com/nexus/3/nexus-3.0.1-01-unix.tar.gz
The issue seems to be related to how the component is stored, as once it occurs it will persist across reboots. There seems to be no way to get rid of it once it occurs, although I haven't tried dumping the repo entirely.
If the offending package is published to another npm repo on the same server, it usually is not affected, so I doubt it is related to the content of the package.
I seem to recall that some of the affected package version ranges used to delete just fine, but I can't be sure of that.
The issue happens fairly often to me, about 1 in every 5 semver-patch ranges seem to be affected.
My workflow may be causing this: I have redeploy off, but tend to play fast and loose when developing, and will commonly delete a semver-patch version if I discover a bug soon after publishing it. Additionally, I tend to scan through the codebase and remove earlier patch versions that are no longer in use.
