Orignal stack trace is from my home laptop's Linux OS Ubuntu 11.10 install using OpenJDK.
Here is the stack trace on my virtual Linux OS Ubuntu 11.10 install using Sun's java:

- Status changed from assigned to closed
- Resolution set to fixed
Johannes pointed out that this has to do with an unconfigured Java compiler. In e23f5a82d4ea99f9a39024308d77c01b48dda694 updated OptionsSynchronizer to safely handle when class loading of the compiler fails.
Perhaps we need to avoid OpenJDK. But I cannot find such a recommendation on our webserver.
