The second-to-the-last bullet in in
http://www.jboss.org/documentation/HTML/ch06s08.html states the following:
"The tag <resizer-period> specifies the period of the resizer, that
is a periodic task that runs (in the above case) every 400 seconds. Purpose
of this periodic task is to shrink / enlarge the cache capacity upon 3 other
parameters (see below). While the period of this task is 400 seconds, the
first run happens at a random time between 0 and 400 seconds. To disable the
resizer set the period to 0."
However, attempting to set the <resizer-period> to 0 results in the
following exception being thrown:
[Container factory] org.jboss.ejb.DeploymentException: Can't import policy
configuration, Cause:org.jboss.ejb.DeploymentException: Resizer period can't

Upon inspecting the code, I find that
org.jboss.ejb.plugins.LRUEnterpriseContextCachePolicy.java version 1.6, line
157 contains the following code:
int p = Integer.parseInt(rp);
if (p <= 0) {throw new DeploymentException("Resizer period can't be
<= 0");}
m_resizerPeriod = p * 1000;
Is this a bug or is the documentation wrong?
