I have a very simple report that uses a scripted data source to access a data sourced class. The class is simple Jersey wrapper class that accesses a Restful service. The report executes correctly within the report viewer preview correctly only the first time. Any subsequent execution fails with the following until Eclipse is restarted.

The report executes correctly every time if deployed to BIRT running on Glassfish.

Reproducible: Always

Steps to Reproduce:
1.Create a simple Java JAX-RS Jersey client to access a RESTFul service
2.Create a report with a scripted data source to access the Java POJO and populate some fields on the report.
3.Set the report runtime classpath to include all the Jersey 1.11 jar files and the Java POJO wrapper class created in 1.
4.Preview the report. It should work correctly the first time. Refresh the report and you will see the ClassCastException.
