And it turns out, I celebrated just a bit too early. Neither the info demo nor the fractal demo directly create a CLContext. The info demo doesn't create one at all and the fractal demo uses the CLGLContext.

One of the demos that actually creates a CLContext is the bandwidth demo, and of course that one doesn't work :(
The stack trace is pretty much what we'd expect:

[java] Exception in thread "main" com.jogamp.opencl.CLException$CLOutOfResourcesException: can not create CL context [error: CL_OUT_OF_RESOURCES]
[java] at com.jogamp.opencl.CLException.checkForError(CLException.java:67)
[java] at com.jogamp.opencl.CLContext.createContext(CLContext.java:225)
[java] at com.jogamp.opencl.CLContext.create(CLContext.java:190)
[java] at com.jogamp.opencl.demos.bandwidth.BandwidthBenchmark.main(BandwidthBenchmark.java:99)
[java] Java Result: 1

I also forgot to include the output from the info demo, here it is:
