Subject [jira] [Created] (CASSANDRA-5611) OS X puts an icon for Cassandra in the dock
Date Tue, 04 Jun 2013 02:09:20 GMT
Aleksey Yeschenko created CASSANDRA-5611:

             Summary: OS X puts an icon for Cassandra in the dock
                 Key: CASSANDRA-5611
             Project: Cassandra
          Issue Type: Improvement
    Affects Versions: 1.2.5, 1.1.12, 2.0
         Environment: OS X, JKD 1.7
            Reporter: Aleksey Yeschenko
            Priority: Trivial

"Even when a Java program doesn't display any windows or other visible elements, if it accesses
the AWT subsystem in some way (e.g., to do image processing internally), OS X will still put
an icon for the Java program in the dock as if it were a GUI-based app. (When the program
quits, the dock icon goes away as usual.)"

(more details at

Can't remember when it started happening, but it wasn't always the case for Cassandra. Now
launching Cassandra puts an icon in the dock, and, worse, running ant test put an icon in
the dock for each test, stealing focus, too. This is extremely annoying.

I ninja-d a workaround (-Djava.awt.headless=true) for ant test in 99824496aa359fcbe5e71f4e54f2738f09524a87,
but we should try and find the real source of this (my guess is that some dependency of ours
is to blame).
