Why does "appcfg.py request_logs" not accept "java" as a valid runtime in app.yaml?

[Krishna Patel]

Is there a way for a Java app to call "appcfg.py request_logs"?

When I try to do so, I get this error which goes away if I kludge my app.yaml by changing the runtime value from 'Java' to 'Python':

appcfg.py request_logs --application=s~example --email=exa...@gmail.com --num_days=1 . C:\request_logs.txt
Host: appengine.google.com
Error parsing yaml file:
Unable to assign value 'java' to attribute 'runtime':
Value 'java' for runtime does not match expression '^go|python|python27$'
  in ".\app.yaml", line 2, column 10

But I don't want to have to remember to change the runtime value every time.

Is there a way to avoid this kludge and download request logs for my Java app?

To download request logs for your java app use this command line instead:

/appengine-java-sdk/bin/appcfg.sh request_logs myapp/war mylogs.txt

Hope this helps!
