Robert Joseph Evans commented on STORM-1226:
--------------------------------------------

Some of the code may need to be left in clojure for the time being, as it only 
makes since in clojure, like clojurify-structure.

> Port backtype.storm.util to java

> Port backtype.storm.util from clojure to java.  In as many instances as 
> possible the same interface should be maintained, and calls to clojure 
> functions in the rest of the code should be replaces with calls to the 
> corresponding java code.
> Some similar functions can be found at  
> https://github.com/apache/storm/blob/jstorm-import/jstorm-core/src/main/java/com/alibaba/jstorm/utils/JStormUtils.java
> Although they are not identical.
> For function callbacks we may need to evaluate adding in appropriate callback 
> interfaces instead.  Please try to avoid using clojure internal java classes 
> unless necessary.
