You're slightly mistaken in your reading of the documentation. When you say 
15 minutes, you are probably referring to 
https://developers.google.com/appengine/docs/python/backends/overview#Billing_Quotas_and_Limitswhere
 it says, "In general, backend usage is billed on an hourly basis 
based on the backends uptime. Billing begins when the backend starts and 
ends fifteen minutes after the backend shuts down." The 15 minute rule only 
applies to billing, not runtime.
 
Backends can be shut down for several reasons, detailed here: 
https://developers.google.com/appengine/docs/java/backends/overview#ShutdownSince
 you managed to fix the problem by eliminating JARs, the problem was 
most likely that your app overran the maximum memory allotted.

"crashed silently" is probably too strong a phrase. It would be more 
accurate to say it was shut down. There should be logs from the backend 
explaining why it was shut down. If you don't see them, try this: go to 
Logs, open up the dropdown list on that page, and select the name of the 
backend from that list.
