Subject Re: Ant 1.7.0 can't find Junit in ${user.home}/.ant/lib
Date Fri, 09 Feb 2007 04:43:16 GMT

Hi Peter,

Can you take another look at this?  I apologize that I did not point 
it out in the original email, but the problem is specifically with 
older JVM's such as JDK1.3.1.  I happened to be using it for building 
the project where I found the problem.  I just didn't realize it was 
specific to JDK1.3.1 until I tried with JDK1.6.  I only tried JDK1.6 
after you failed to reproduce the behavior and I saw you were using JDK1.5.

I think this got lost in the shuffle of the current religious debate 
over whether XML is a scripting language.  How about we fix this 
issue first and then move on to that never-ending debate.  BTW, 
everyone realizes that the Gant project exists, right?
