You are using Oracle TopLink Worbench (10.1.3) and reading information from the Welcome page (Help->Welcome Page). Under the "Get Started" and "More Information" you are able to access the next web page from the links in those areas, but if you navigate further from that page you encounter the following error:
java.lang.UnsupportedOperationException
For example, under "Get Started" click on the "Quick Start" link, which opens a new page titled "TopLink Quick Start" containing the links: Understanding TopLink, Working With TopLink Workbench, Creating a Project, Creating a Descriptor, Creating a Mapping, Deploying a TopLink Application, Optimizing and Customizing a TopLink Application. Clicking on any of these links results in an Unexpected Error dialog box:
