Comments
EVALUATION Hprof binary format dump is created by jmap when used with command line option -heap:format=b. When jmap is run with the new option, it produces 'heap.bin' in current directory. The heap.bin can be used with Heap Analysis Tool (HAT). Please refer to http://ccc.sfbay/5109224 for specification and other details. Refer to "Suggested Fix" for Webrev URL and attachement (webrev.tar). ###@###.### 10/29/04 08:48 GMT
