jmap / jhat -baseline problem

hi,

i'm trying to use jmap to generate two heap dumps and then use jhat with option -baseline to compare them to see what objects were added (ie. track a memory leak). however, the instance/object ids seem to change from dump to dump. i tried logging the creation/finalization of some objects, and while i can see that they are certainly created only once and never finalized, their ids are different on different dumps. i also tried to use jconsole and the heap dump mx bean operation, and got the same results. i'm using jdk 1.6.0b105 64bit . can you please point me to some docs or suggest what am i doing wrong, please?

thanks & regards

peter
