Re: [ecf-dev] zookeeper with standalone osgi 
Hi Wim,

It seems the Execution Environment for the org.apache.zookeeper bundle 
is currently set to JSE1.5...i.e.

in /org.apache.zookeeper/META-INF/MANIFEST.MF

Bundle-RequiredExecutionEnvironment: J2SE-1.5

Given what you say about apache zookeeper req for 1.6, should this EE be 
1.6?  If so please open bug and repair (hopefully in time for RC3 the 
end of this week).

Thanks,

Scott
