Thanx for ur response, Actually We are using string builder in our project, String Builder causing the memory leak in as I google, Thats the main reason i want to set the StringBuilder object to nil, We are using the htmlunit core js library for fetching the web pages which require the javascript enabled. The Decompiler.java using a variable StringBuilder result = new StringBuilder(); Netbeans profiler showing that this is the object consuming maximum of memory causing memory leak. Thats the reason only I want to set the StringBuilder object in our project to null. I also found on net that strbuilder.toString() also causing the memory leak. So in place of toString() we are trying to use substring(0). As u have written that in java term, they are final but its allowing me to set the length after declaration. like:
(defn #^String element-text ([thing] (let [delimiter #s""] (element-text thing delimiter) )) ([thing #^String delimiter] (if (instance? Node thing) (node-text thing) (let [buf (StringBuilder.)] (doseq [#^Node e thing] (node-text e buf delimiter)) (let [res (.substring buf 0)] (.setLength buf 0) res))))) If I am wrong, Then pls suggest me right way to do this thing.
