I am using rp5 version 1.0.8, installed using gem.

[jurisgalang]

Might be a different issue, but I think I've seen this before - I had my default Java set to Java 6.

[jashkenas]

What Java version are you using? It's working just fine for me on 10.5 with Java (build 1.5.0_16-b06-284)

[jashkenas]

It's also working for me on 10.5 with Java 6 (build 1.6.0_07-b06-153). Are there any more details about your setup you can provide?

[ryszard]

I have the exact same versions of java as you. I tried to run the example with both, and with both I get the same error :( Is there any more information about my setup that may help you reproduce the bug? I don't know Java and I am very new to Ruby, so I hardly have a clue about what could be useful.

[jashkenas]

So, you're getting a RendererChangeException, which is something that Ruby-Processing's patched version of Processing' core.jar should be catching, and handling. Did you replace core.jar? If not, try running this instead, which uses a slightly different flavor of sketch creation:

[ryszard]

I haven't replaced core.jar. Running the new script you provided I still get the exact same error. I also tried to reinstalling the gem, which also didn't help.

[jashkenas]

Then two questions ... does ruby-processing fail on any other sketches aside from the camera ones? And what architecture does your machine have (64-bit, 32)?
