Exception when trying to retrieve object from database
I am getting the following exception:

We are using JDK 1.5 .. and my boss thinks that this may be due to its auto boxing feature, and it trying to deserialize a java.lang.Boolean and interpreting it as boolen instead.
You may note that the setup and start of the cache is working fine. Its just when I try to retrieve an object from the database, do I get this error.
Any help will be appreciated.
Thanks
