Hi. Thanks for this. The minimum Java version is 11 due to a Lucene minimum Java requirement. The penultimate release was accidentally built using JDK21 and so that uberjar did require version 21 or higher, but this was fixed in the most recent release (see bcc0df1) so the latest release should work with 11 and above. You should also find running from source code using the clojure command-line will work so long as you are on Java 11 or above. The latest Lucene (v10) requires a more up to date Java however. You can opt-in to using Lucene10 if you using JDK21 or above when running from source code e.g. clojure -M:lucene10:run --db mydb.db --serve - there is conditional compilation to handle the minor compatibility changes between Lucene 9 and 10 series.

Hello Mark, thanks for your swift reply!
ok, so Java 11 is the current min. required Java version. Would it make sense to state that in the Readme.md?

Thanks, Thomas

Good idea!
