The faulty BeanShell call means the Switch value is treated as a name;
it does not find the name, so does not run any samplers. The same
happens if the condition is set to "xyz" for example.

The lack of any samples causes a problem for the Thread Group.
If you add a sampler after the Switch Controller, the test plan works fine.

Whether a similar fix would work for your original test case, I don't know.
Might be worth a try if you can work out where the test is failing.
