> "JDBC 4.0 functionality is not enabled in this Derby release. JDBC 4.0 is part of Java
SE 6, which was not generally available for Derby 10.2. When you use Derby with a Java SE
6 virtual machine, JDBC 3.0 is available. JDBC 4.0 is available only to developers who download
Java SE 6 and use it to add JDBC 4.0 support to Derby. The Release Notes explain how to build
the JDBC 4.0 functionality with Derby 10.2. When Java SE 6 becomes generally available, a
follow-on Derby release will include final JDBC 4.0 functionality. "

- I think 'was not generally available at the time of the Derby 10.2 
release' is  a better phrasing

- 'JDBC 3.0 is available' is confusing to me -- available for what?  I 
think.  Also, note that JDBC 3.0 is also what you are using with 1.4 and 
1.5 VMs.  So I think better wording is:

'When you use Derby with a Java SE 6 virtual machine, Derby will use its 
JDBC 3.0 drivers, just as with 1.4 and 1.5 virtual machines.'

- Also 'download Java SE 6 and use it to add JDBC 4.0 support' should be 
more clear: 'download Java SE 6 and use it to build in support for JDBC 4.0'

be addressed in the Release Notes.
