Well, this bug is rather hard to reproduce, but the following sequence does 
reproduce 
it regularly on my machine:

"D:\Program Files (x86)\Java\jdk1.6.0_16\bin\java" -cp 
D:\workspace\test\bin;D:\workspace\test\lib\google-collect-1.0-rc3.jar Test

Open monitor tab in Java Visual VM for the process.

Invoke heap dump, wait for it to complete and switch back to monitor tab.

I'm attaching my sysinfo.

This issue has been moved to the Guava project (keeping the same id number). 
Simply replace 'google-collections' with 'guava-libraries' in your address 
bar and it should take you there.
