Hi 

I am experiencing an intermitent problem of GAE jetty 9.0 crash. The crash 
is not caused by a specific restful call. Once GAE jetty 9.0 crashes, the 
service  (the application) is not accessable anymore and all instances have 
to be restarted. Have anyone seen the same problem and managed to get full 
stacktrace logs to find the root cause?

Here is the complete log. on GAE java standard environment, 
XX:-OmitStackTraceInFastThrow 
is not supported. any help on getting the full stacktrace is real 
appreciated.
