as of today, eclipse only shows 5 warnings about the zookeeper main codebase,
including tests. The remaining 5 should rather be solved by somebody knowing
the code better then me.
Would you like to make it a policy that new changes may not introduce new
warnings (at least not without a very good reason)?
There are however another 300+ warnings in contrib/loggraph.
I've filled these issues:
ZOOKEEPER-1245 fix compiler warnings in contrib loggraph
ZOOKEEPER-1244 resolve remaining compiler warnings
