Evergreen asked me to send a report so here it is:
Uncaught exception
An error occurred in Evergreen:
Exception RuntimeError: Java failed with #<Process::Status:
pid=27480,exited(1)>
Please send us the contents of the application log, from /tmp/edit.log.
27459.
The log was empty so I have not attached it.
An idea of what you were doing when Java exited might be useful.
I was launching evergreen from the Applications>Programming menu; I
am not sure that I have ever done so before on this machine.
