Subject Re: svn commit: r689244 - in /geronimo/server/trunk/plugins/openejb/geronimo-openejb-clustering-wadi/src: main/java/org/apache/geronimo/openejb/cluster/stateful/container/ test/java/org/apache/geronimo/openejb/cluster/stateful/container/

Guess we need to build OpenEJB trunk locally until a new SNAPSHOT is 
published?  I'm getting build errors on trunk r689302 now even after 
removing openejb from my local repo -
