I am wondering if it possible to control the sizeOfPolicy on
shiro-activeSessionCache? I am using shiro with terracotta, but I am
not sure how I can change the 'behavior' and the 'maxDepth'? Here is my
current config:
<cache name="shiro-activeSessionCache"
overflowToDisk="false"
eternal="true"
timeToLiveSeconds="0"
timeToIdleSeconds="0"
maxBytesLocalHeap="100M"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="600">
<sizeOfPolicy maxDepthExceededBehavior="abort" maxDepth="500" />
<terracotta>
<nonstop immediateTimeout="false" timeoutMillis="30000">
<timeoutBehavior type="exception" />
</nonstop>
</terracotta>
</cache>
Yet I am still seeing:
WARN ObjectGraphWalker:209 - The configured limit of 1,000 object
references was reached while attempting to calculate the size of the
object graph. Severe performance degradation could occur if the sizing
operation continues. This can be avoided by setting the CacheManger or
Cache <sizeOfPolicy> elements maxDepthExceededBehavior to "abort" or
adding stop points with @IgnoreSizeOf annotations. If performance
degradation is NOT an issue at the configured limit, raise the limit
value using the CacheManager or Cache <sizeOfPolicy> elements maxDepth
attribute. For more information, see the Ehcache configuration
documentation.
As a result, I am getting alot of:
ERROR AbstractShiroFilter:317 - session.touch() method invocation has
failed. Unable to updatethe corresponding session's last access time
based on the incoming request.

Which am assuming is because I am attempting to access the same
collection that the ObjectGraphWalker is attempting to access.
Is there any way to set the sizeOfPolicy either via ehcache.xml or via
shiro.ini?
Thanks
