> It looks to me like the TomcatJAASRealm (its name is "DefaultJAASRealm") is a
> standard realm that is used by all WARs without explicit configuration.
> Setting the realm of a GeronimoStandardContext makes the context store a
> reference to its realm AND makes the realm store a reference to the context
> (see org.apache.catalina.core.ContainerBase#setRealm() which
> GeronimoStandardContext inherits). Thus, the default realm's reference is
> always directed to the context of the WAR deployed most recently. This
> reference keeps the context from being GCed even if the corresponding WAR has
> been undeployed in the meantime.
