Hello Michael, I have shared my code with you on you emailId.
Second thing, I am trying myself and analyze heap dump using mat ( eclipse memory analyzer) then I found most of memory (96%) is consumed by java.utils.HasMap$Entry class and there are more than 64000 such objects .. I am not able to attach heapdump becuase it is of 500MB around .. Thanks On Wednesday, 23 April 2014 01:22:00 UTC+5:30, Michael Hunger wrote: > > Perhaps you can share your full code?
