JDK 1.6.0_45 Vs JDK 1.6.0_21 - Jacob API

JDK 1.6.0_45 Vs JDK 1.7.0_21 - Jacob API

I used the Jacob API with JDK 1.6.0_45 and JDK 1.7.0_21.
In JDK 1.6.0_45.When I executed the List Users Code with Jacob API,

Refer ,

http://blogforopensource.blogspot.com/2014/01/list-windows-users-java.html

the code crashed exactly while running for 12th Time.
I run this code in Windows Server 2008 R2, 64 bit in a Virtual Machine created Under Xen.

Here is the crash report.

When I run the same code in JDK 1.7.0_21, this error does not arise.
I run this code for 200 Times, upto which the program never crashed.
So Is this a JDK version problem ? or the Jacob API compatibility problem with JDK ?
