Subject Re: [classlib]Self-host of Derby
Date Fri, 13 Oct 2006 10:24:26 GMT
Hi Leo,

I have uploaded my patch to the Wiki.  However the patch just forces use of
the jdk15 support class, in order to get the tests up and running.  As you
say, a better solution would be to have our own support class.

Regards,

Sian
