Heap dump which causes the exception in NetBeans. Created by hprof-conv from an Android heap dump.

Sure! Here it is. Maybe it matters that this heap dump was created from an Android heap dump by the hprof-conv tool from Android SDK. However, I tried opening it with the jhat tool, and it didn't complain.
Comment 4 Tomas Hurka 2011-09-07 13:35:22 UTC
Thanks for the heap dump. BTW: Next time, please compress the heap dump using zip, gzip, etc.
