Spring-webflow SnapshotCreationException Error after login

I am working with a java project with spring-webflow and fimefaces 3.3.
The version of primefaces cannot be increased due to menu developments and other components that generate an error when trying to upload the version. The problem is not this.

The problem comes from setting the max-execution-snapshots property. If I put a value other than 0, it generates the exception indicated by the statement.

I thought that it could be the objects that some were not serialized, but I have implemented serialization and it continues with the same result.
Before refactoring the project, passing it from ant build to Maven, it was not necessary to indicate in the flow-executor the flow-execution-repository. The most curious thing is that they are the same libraries that are used:
spring-faces-2.4.1.RELEASE, spring-webflow-2.4.1.RELEASE and the rest of spring are 4.3.16.RELEASE.

When the application loads, it makes a call to return a list, but this is not the fault. I guess the problem must be in the call to the WebService because the error it throws in the rootcase is: java.io.NotSerializableException: org.apache.cxf.jaxws.JaxWsClientProxy

I don’t know if it’s also a problem with the filters, I don’t know exactly. I have been looking for a solution for several days, but it has not been possible.

I put here the stacktrace and the spring-webflow configuration
Thanks in advance!
