Happens with both beta3 and latest svn (468820).
What's interesting, ecj 3.2 works fine. But since it's different branch and not
just bugfix of 3.1, I believe it's still worth fixing. Also, ant 1.6.5 works
with both ecj 3.1 and 3.2 which suggests the problem is in ant, not ecj?

fixed in SVN. Workaround is to set the Project attribute to FileSet in
Path#addFileset. Did the same for FileList, Path, and DirSet.
Root cause of the problem is org.eclipse.jdt.core.JDTCompilerAdapter.java . In
the version 3.1 of Eclipse, a FileSet is created in the method addExtDirs(Path,
Path). The Project attribute is not set on this FileSet, but it is added to a
Path. When Path.toString() is called, this leads to a NullPointerException. I
suppose that this is done differently in Eclipse 3.2.

Can you add your build file to the bug report ? Or ideally just the piece which
is necessary to find the error.

Created an attachment (id=19049)
--> (http://issues.apache.org/bugzilla/attachment.cgi?id=19049&action=view)
simple build file exploiting the bug
"ant prepare" creates the .java file to compile, "ant" compiles it,
build.compiler property is pre-set to ecj, you just need to supply ecj.jar via
-lib parameter
you can download sources of ecj here, to spare downloading of whole eclipse
sources (they are just unpacked directly from there), there are also build
files for creating ecj.jar for testing
