Then at least the eclipse.exe java starter does not hide&drop the
messages...

Still, your problem beats me. I have a headless application that uses
System.out to print own messages and runs an ant script via AntRunner,
echo and output messages from the script show up using
antRunner.addBuildLogger("...DefaultLogger").
Then I have the headless application wrapped in my own ant task. Running
a build file using this custom ant task with the antRunner application
from the command line shows output from the outer script, the task, the
headless application and the inner scripts without a problem...

(I'm using Eclipse 3.1.2) What you do should work as well (probably set
up a very small test for your situation?)...
