For certain versions of plugins, Openfire incorrectly identifies that an update is available. When Openfire has installed `10.1.7.3-SNAPSHOT` it incorrectly identifies that version `10.1.7.2` is an update. This seems to be caused by Openfire’s abuse of the 4th numeric value in a version. It was originally intended to be a classifier for the status (eg: ‘the second beta release’). When that 4th value is used as part of a four-digit version, things do not quite compare as expected. To illustrate, compare these two scenarios. The numbers 3 and 2 are all stored in the same field, which gets interpreted differently. - `10.1.7 beta 3` is older than `10.1.7 release 2` - `10.1.7.3-SNAPSHOT` is expected to be newer than `10.1.7.2` (release). Prior to this commit, Openfire did not flag that `10.1.7.3-SNAPSHOT` is newer than `10.1.7.2`, which was causing confusion. In this commit, _only_ the `SNAPSHOT` release status is now compared differently (as if the 4th value is part of the version string). (cherry picked from commit 72b67cb)
