Apache Derby must run at a minimal version of v10.3 or Cloudscape v10.1x. The Apache Derby package that is bundled with the application server is backed by full IBM® Quality Assurance (QA).
Unlike versions 5.1.60x and earlier, Apache Derby is a pure Java database server. The Apache Derby code base, which the open source community calls Derby, is a product of the Apache Software Foundation (ASF) open source relational database project. Apache Derby includes the Derby base code without any modification to the underlying source code. You can investigate more incompatibilities about Derby code at the Apache Derby web site.
