blank lines in netbeans output

hello, i have a strange problem:
when i run my jogl app from netbeans, blank lines appear in the output window, but i don’t output any text from my app.
there are no errors, app runs fine, but it’s quite strange…
here’s the output:

init:
deps-jar:
compile:
run:






















BUILD SUCCESSFUL (total time: 7 seconds)

any ideas?
