Subject Re: JDBC 4 and build sanity
Date Mon, 29 Sep 2008 06:56:18 GMT
Good idea about OpenJDK BTW... maybe I'll hack a little Maven module  
based on OpenJDK with needed interfaces and post on on ObjectStyle.  
Then we can have it as a "provided" (i.e. not bundled) dependency for  
cayenne-jdk15-unpublished.

Let me float that on legal-discuss.
