increasing fd when running JBoss with Terracotta

We're running JBoss 4.05 with Terracotta 2.4.3 and noticed a strange behaviour.
The file descriptors associated with the JBoss process appears to increase
continuously as soon as it is started. It increases until it hits the limit and
then we start seeing "too many open files" messages in the jboss server log. We
don't see this behaviour when running JBoss without the TC libraries.
We've tracked this down and feel pretty sure that it relates to the
UrlDeploymentScanner of JBoss (which is used for hot deployment). As I
understand it, TC instruments the JBoss UCL and org.jboss.Main class. Could
this have inadvertently affected the deployment scanner? If so, is there a
solution to it via configuration or code patch (other than turning off the
scanner, of course)
