| public com.sun.enterprise.tools.verifier.Result | check(com.sun.enterprise.deployment.EjbDescriptor descriptor)The Bean Provider should not declare the session bean fields in the session
bean class as transient.
This is to allow the Container to swap out an instance's state through
techniques other than the Java Serialization protocol. For example, the
Container's Java Virtual Machine implementation may use a block of memory
to keep the instance's variables, and the Container swaps the whole memory
block to the disk instead of performing Java Serialization on the instance.
