I am setting LRU Eviction policy with miltiple regions but it seems like maxNodes settings
are not respected. I read the following xml and use setEvictionPolicyConfig(Element
a_config) so set policy. Region /reportDefinition/extraInfo is setup to live 30sec and
have max node of 2 but when I dump my cache I see 5 nodes. Cache dump output is at the end
of this post.
Here is the XML for eviction :
| <config>
