Site toolkit doesn't log pool size on NoAvailableSessionException

It would be very useful if the message below would actually log some info about the pool, for example the size, the pool name, etc:

Mar 29 07:15:08 org.hippoecm.hst.core.component.HstComponentException: org.hippoecm.hst.core.jcr.pool.NoAvailableSessionException: No session is available now. Probably the session pool was exhasuted.
