Subject No licensing issues anticipated for building JDBC 4.1 support into Derby 10.8
Date Tue, 14 Dec 2010 19:44:39 GMT
As part of 10.8, it would be good to implement JDBC 4.1, a smallish set 
of changes which are part of the larger Java 7 effort. The JDBC 4.1 work 
is described by the functional spec attached to DERBY-4869.

The good news is that we will not face the licensing hurdles which 
complicated the release of JDBC 4.0 functionality in Derby 10.2. You may 
recall that we were not allowed to use the early access Java 6 compiler 
in order to build a product. That meant that we could not compile our 
JDBC 4.0 support into the first release of Derby 10.2.

The same restriction applies to the early access Java 7 compiler. 
However, we do not need to  use the Java 7 compiler in order to build 
the JDBC 4.1 bits. That is because we will not need any new classes or 
language features introduced by Java 7.

In short, we should be able to build Derby 10.8 purely with the Java 6 
compiler. I do not anticipate any licensing problems with the 10.8 release.
