I get an exception clicking on any packages (on 
the left).
It makes the Object Browser completely unusable.
Is there something I can do to make it work, it 
is a very important tool for me.

The org.openide.DataFolder.getChildrenList() is 
package 
private. When called from the 
org.openide.loaders.DataObjectFilter$4 it yields 
an 
IllegalAccessError. This might seem 
inappropriate since 
they actually reside in the same package.

My guess is that the offending class is loaded 
using a 
different classloader. From a security 
perspective, that's 
the same thing as residing in different package.

This is the exception detail:
