Description

« Hide

Per discussion in ~~DERBY-3243~~, Network Server stores a duplicate entry in the lob hashmap for every lob. I posted a preliminary patch to ~~DERBY-3243~~ and received comments on the patch in that issue, but it makes more sense to separate the issue out from ~~DERBY-3243~~. So opening up this new issue.
