Builds are failing at beginning of execution when using the Subversion plugin for checking out source.

We run Jenkins as a Windows Service on Master.
Slaves are controlled via SSH.
Java Heapspace: (master)-Xmx1250m -Xms256m, (slaves) -Xmx2g -Xms256m
Java VM is Oracle

Not sure if I am reading this stack exception, something with how data is being deserialized on the client side?
