Dag H. Wanvik commented on DERBY-6059:
--------------------------------------
Kim, your reading is very observant. I believe at one point (DERBY-5880), we
were able to move that 4.0 specific additions into the plain data sources,
making the suffix "40" a tad confusing indeed. Using the "40" data sources for
Java 1.6 (jdbc 4.0) is still fine, it is just no longer required (and they are
slightly more capable than required by 4.0). For Java 7 (JDBC 4.1) it *is*
required. Ideally, the classes would now be suffixed with "41"...

> Document that Derby can run even under constrained Java runtime as planned
> for Java 8 Compact Profiles 2 and 3 (not 1, the smallest runtime, since it
> has no JDBC). Cf work in DERBY-5955 which made Derby run gracefully even when
> some normal Java runtime packages are missing, notably JNDI and JMX.
> That work introduced six new data sources which have reduced functionality
> compared with the corresponding ones for full Java SE, in that there is no
> JNDI support. The six new data sources are for the client driver:
> Client/server data sources for use with Java 8 Compact Profile 2 and above:
> BasicClientDataSource40 - Data source
> BasicClientConnectionPoolDataSource40 - Connection pooling data source
> BasicClientXADataSource40 - XA data source
> Embedded data sources for use with Java 8 Compact Profile 2 and above:
> BasicEmbeddedDataSource40 - Data source
> BasicEmbeddedConnectionPoolSource40 - Connection pooling data source
> BasicEmbeddedXASource40 - XA data source
