Incompatibility Between Pre-1.1.6 and 1.2 Databases

Cloudscape uses serialization in its system catalogs and when storing user objects. JDK 1.2 writes out serialized streams in a format different from that of JDK 1.1 releases. If you create a database, or manipulate it, using JDK 1.2, it can be used only with JDKs of version 1.1.6 and higher. JDK 1.1.6 and higher versions can read both formats of serialized streams.
