There was a refactoring done a while back that removed the threaded 
aggregation by default:

http://cvs.apache.org/viewcvs.cgi/jakarta-jetspeed-2/portal/src/java/org/apache/jetspeed/aggregator/impl/PageAggregatorImpl.java?r1=1.18&r2=1.19&diff_format=h

I know the purpose of the refactoring was to make the improve the 
aggregator, but not sure why it removed (and broke) multithreading

My vote is to hold the release until this is fixed

-1 on the M2 release until multithreaded aggregation (which worked in 
M1) is fixed
