Memcache problems
James Broberg
Just set up a new dev environment on Linux with an existing codebase
of mine and came across an odd error I hadn't encountered before.
Has anyone seen the below error? I'm fairly certain memcache is the
problem, not appstats, as I get a similar "java.lang.NoSuchFieldError:
alwaysUseFieldBuilders" error any time I do anything memcache related.
HTTP ERROR 500
Problem accessing /stats. Reason:
alwaysUseFieldBuilders
Caused by:
java.lang.NoSuchFieldError: alwaysUseFieldBuilders

I got this error while running my tests. It started when I updated
from an older version of the App Engine SDK to 1.4.2. The jar files I
had on my integration test classpath were from the old version and I
needed to update them by overwritin them from the new distribution.
The files in question were:
appengine-api-labs.jar
appengine-api-stubs.jar
appengine-api.jar
appengine-testing.jar
And appengine-testing.jar is actually on the classpath for compiling
the tests, the others are just required as runtime dependencies.
Cheers,
Ashley
