Would you be so kind and fill here some additional notes such
what have you been doing while this exception appeared,
if this is happening randomly or all the time and if you
have some reproducible scenario how to simulate this problem
write it here as well.
Its hard to track down core of issues just from attached exceptions.

The exception repeated a number of times while I was attempting to load 
netbeans 5.5 on one occasion.  It has not reoccurred, so I am happy if you 
want to resolve it as "unreproducable".  However I always feel that it is 
important to report problems so that if problem patterns occur you have a 
range of potential debug materials available.
