When the number of request exceeds the number of view stored in the session,
the following exception is thrown:
com.tc.exception.TCNonPortableObjectError:
*******************************************************************************
Attempt to share an instance of a non-portable class referenced by a portable
class. This
unshareable class is a subclass of a JVM- or host machine-specific resource.
Please either
modify the class hierarchy or ensure that instances of this class don't enter
the shared object
graph.
Referring class :
org.apache.commons.collections.map.AbstractReferenceMap$ReferenceEntry
Referring field :
org.apache.commons.collections.map.AbstractHashedMap$HashEntry.value

A minimal war has been attached. The number of views stored in the session has
been reduced to 5, in order to replicate the problem quicker. To reproduce,
deploy the war in the Terracotta Session Configurator, point the browser to one
of the servers and reload the page 5 times.
