I have a thread dump and Memory dump of my process where a thread is hung

```

But I need to see what object is at the memory location 0x000000070feebf40 . Is there an easy way to see this object ? Both YourKit and jvisualvm does not see what is in at this memory address.

I tried looking by instances but there are 300 of them for most of them which makes it really difficult to analyze.

I have used C# and there you can easily search the memory using WinDbg and sos plugin.
