[jboss-user] Setting maxSpareThreads and minSpareThreads doesn't do anything in JBoss 4.2.0.GA

I'm running JBoss 4.2.0.GA and I want limit the number of unused idle threads. This is supposed to be possible using maxSpareThreads and minSpareThreads but neither option seems to do anything: <Connector maxThreads="100" minSpareThreads="10" maxSpareThreads="30" ... /> JBoss always starts with only one active thread, and if it needs to create 100, it'll keep 100 alive, even if the load drops down to nothing. Is there a way to do this? Thanks, Raul Acevedo http://www.cantara.com
