Hi folks,
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
