Failing to load processes after installing patch 10.1.2.3

Question

I have installed patch 10.1.2.3 after Oracle advised that it may resolve some database adapter problems I was getting in 10.1.2.0.2. However after installing the patch, many of the BPEL processes are now failing to load when I bounce the OC4J component and I am getting ORABPEL-05215 errors.
I turned on debug logging and an extract of the log file is as follows, has anybody got any ideas on how I might resolve these errors;

Answer 1

I forgot to mention that I did flush the JAR cache to make sure the new JAR's would be downloaded.
