GAE doesn't like user code calling ThreadGroup.getParent() (line 597 of TapestryInternalUtils, in your stack trace) which seems an unnecessary restriction given that access to Thread.currentThread().getThreadGroup() is allowed. I wouldn't be surprised if there was a bug open against GAE on that.
Anyway, you can certainly get it to work on GAE as well. The simple answer is that you probably don't want to show the development exception page on production anyway. Beyond that, you might need to override ExceptionReport.getThreads() to return perhaps just the current thread. I don't think the default behavior of Tapestry should change just for GAE.
