> The content of the generated {{Log4j2Plugins.dat}} does not appear to be repeatable. I noticed the problem as it affects Gradle's build caching. Getting different output from Java compilation for the same inputs causes a cache miss and additional work that should be unnecessary.
> Looking at the code, I believe that the problem is that {{PluginProcessor.process}} works with a {{Set}} of elements and that {{PluginCache}} uses an insertion-order map. If the order of the elements in the {{Set}} changes, they will be inserted into the cache in a different order and then written out in a different order.
> Would it be possible to use {{TreeMap}} s in {{PluginCache}} so that the categories and their entries are written in name order?
