How do I obtain the type of a Java instance in Jython?

from java.util import LinkedList
type(LinkedList())

The code above only gives "type 'javainstance" as output, however I wish to know the real Java instance type, which should be "LinkedList" in that case. Is this possible?

Thank you!

by the way, my version is jython 2.2.1

I think you should be able to use 

lst =LinkedList()
lst.class

Similar to the way that you would in java.

Howard, if you are on older Jython then try to call

LinkedList.getClass()

and

object.getClass().getName()

Just installed the latest jython last night. Let's take a look...

Jython 2.5.3rc1 (2.5:8fd14231e553, Aug 7 2012, 10:29:09)
[Java HotSpot(TM) 64-Bit Server VM (Sun Microsystems Inc.)] on java1.6.0_31
>>> type(LinkedList)
<type 'java.lang.Class'>
>>> l = LinkedList()
>>> type( l )
<type 'java.util.LinkedList'>

What version of Jython do you have? I know from experience that some levels of inspection only appeared in later versions.
