>                 Key: STORM-3172
>                 URL: https://issues.apache.org/jira/browse/STORM-3172
>             Project: Apache Storm
>          Issue Type: Bug
>          Components: storm-core
>    Affects Versions: 1.2.2
>            Reporter: Chris Bowdon
>            Priority: Major
>
> Attempting to run `storm jar` with something built on Clojure 1.8 or higher fails with this error:
>  "NoSuchMethodError: clojure.lang.Utils.loadWithClass".
> It turns out this method was added to Clojure's `gen-class` in version 1.8 (for reasons to do with serialization that honestly I don't fully understand: [https://dev.clojure.org/jira/browse/CLJ-1157]).
> To reproduce the error try running the storm-starter project with this lein project definition at storm/examples/storm-starter/project.clj:
> {code:java}
> (defproject clojure-gen-class-error-example "0.1.0-SNAPSHOT"
>   :license {:name "Eclipse Public License"
>             :url "http://www.eclipse.org/legal/epl-v10.html"}
>   :dependencies [[org.clojure/clojure "1.9.0"] 
>                  [org.apache.storm/storm-core "1.2.2"]]
>   :source-paths ["src/clj"]
>   :aot :all
>   :main org.apache.storm.starter.clj.word-count)
> {code}
> And then run against Storm 1.2.2:
> {noformat}
> $ lein uberjar
> $ storm jar target/clojure-gen-class-error-example-0.1.0-SNAPSHOT.jar
> ==>
> Running: /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -client -Ddaemon.name= -Dstorm.options= -Dstorm.home=/apache-storm-1.2.2 -Dstorm.log.dir=/logs -Djava.library.path=/usr/local/lib:/opt/local/lib:/usr/lib -Dstorm.conf.file= -cp /apache-storm-1.2.2/*:/apache-storm-1.2.2/lib/*:/apache-storm-1.2.2/extlib/*:/clojure-gen-class-error-example-0.1.0-SNAPSHOT.jar:/conf:/apache-storm-1.2.2/bin -Dstorm.jar=/data-processor.jar -Dstorm.dependency.jars= -Dstorm.dependency.artifacts={} org.apache.storm.starter.clj.word_count
> Exception in thread "main" java.lang.NoSuchMethodError: clojure.lang.Util.loadWithClass(Ljava/lang/String;Ljava/lang/Class;)Ljava/lang/Object;
> 	at org.apache.storm.starter.clj.word_count.<clinit>(Unknown Source)
> {noformat}
> However switching down to Clojure 1.7.0 in the project.clj (matching storm-core) makes this example work correctly. I assume upgrading the dependency in storm-core to 1.9.0 would resolve the problem. It's also a good idea because Clojure 1.7.0 is quite old now (released Jun 2015, 1.8.0 was Jan 2016 and 1.9.0 was Dec 2017).
> Apologies if this upgrade is already planned, I searched the tickets here and couldn't find anything.
