I just upgraded my trinidad jars to 1.0.7 and testing the code below still raises the expand all issue. If I put a value as low as 15 into the test, the expand all no longer works for me. Still I'm uncertain if this is desired behavior or not since it is called out in the developer handbook.
Also, when I use the latest jars, if I use a value as high as 5000, I get an exception that I never used to get with the old version I was running: 26 Mar 08 10:52:26, ERROR [http-0.0.0.0-18080-2]
