Subject Ant 1.7 NullPointerException AbstractFileSet
Date Mon, 17 Apr 2006 10:43:20 GMT
Hi,

During the course of trying to debug this memory problem with 
AppFuse/Ant, I've come across a NullPointerException in 
AbstractFileSet.setupDirectoryScanner : 462

It seems as if the project variable is null so the method p.log fails

Running the same test on Ant 1.6.5 works fine and I can't see any 
changes to AbstractFileSet since 1.6.5 was released (June 2005).

Anyone have any idea why the project isn't set?

works
JDK1.5
Ant 1.6.5

fails
JDK1.5
Ant 1.7 (trunk) compiled today against JDK1.5

Windows XP SP2
