com.tc.exception.TCNonPortableObjectError: 
*******************************************************************************
Attempt to share an instance of a non-portable class referenced by a portable class. This
unshareable class has not been included for sharing in the configuration.

For more information on this issue, please visit our Troubleshooting Guide at:
http://terracotta.org/kit/troubleshooting

Referring class   : org.springframework.security.context.SecurityContextImpl
Referring field   : org.springframework.security.context.SecurityContextImpl.authentication
Thread            : http-8080-1
JVM ID            : VM(1)
Non-included class: org.springframework.security.providers.rememberme.RememberMeAuthenticationToken

Under most circumstances, you should only be adding classes for your
application. If you are adding classes for frameworks or code not written by
you, then you should consider finding a Terracotta Integration Module (TIM)
that matches the framework you are using.

As an example, if the non-portable class listed below is
net.sf.ehcache.CacheManager, you should consider using the ehcache TIM.

It is also possible that some or all of the classes above are truly
non-portable, the solution is then to mark the referring field as transient.
For more information on non-portable classes see the Troubleshooting Guide.

Action to take:

1) Reconfigure to include the unshareable classes
   * edit your tc-config.xml file
   * locate the <dso> element
   * add this snippet inside the <dso> element

       <instrumented-classes>
         <include>
           <class-expression>org.springframework.security.providers.rememberme.RememberMeAuthenticationToken</class-expression>
         </include>
       </instrumented-classes>

   * if there is already an <instrumented-classes> element present, simply add
     the new includes inside it
