Hi Muhammad,
This is normal behavior. The windows task manager just shows the
memory usage of each process. For Java processes, task manager does
not distinguish between memory in use and memory that can be freed by
Java's garbage collector. You need a profiler to see the real memory
usage of a Java process, e.g. YourKit, JProfiler.

Hi Dany,
Thanks for your prompt reply! I am sending you 2 snapshots. First
one contains initial memory dump and the 2nd one contains after
collapsing and expanding same node. Although the memory increase is
not much but in our application where we uses extended
DefaultMutableTreeNode with renederer, memory jump is enormous on
client jvm and seems like its never garbage collected. Extended
DefaultMutableTreeNode creating lots of hashmap/string objects
instances, which are not getting freed even after Forced Garbage
Collections.
I saw related issue (https://www.canoo.com/jira/browse/UBA-7302)
that you fixed recently but not much detail is available. It will
be great if you post some more detail.
I truly appreciate your help in this regard. Thanks again!

Hi Asif,
I could not reproduce the behavior you describe. Here is what I did:
* I started the ULCSet sample with help of the
ULCSetDevelopmentLauncher class
* I selected the TableTree tab in the main window
* I opened the "System III" node in the table tree
* I took a memory snapshot with a profiler
* I closed / opened the "System III" node for several times
* I took another memory snapshot with a profiler
* I compared the two memory snapshots
The comparison of the two memory snapshots showed no irregularities.
Could you please tell us how you identified the memory leak? Thanx!
Regards Dany

Hi,
Expanding and collapsing same tree node keep on increasing client
JVM memory usage. I have even noticed the same behavior in your
demo (http://www.canoo.com/ulc/demos/wfbrowser.html) for tabltree
component. Its look very critical issue. is there any workaround?
thanks in advance.
Kind Regards,
-Asif
