I am doing the following in PHP:
exec('java -jar "/opt/flex3/lib/mxmlc.jar" +flexlib "/opt/flex3/frameworks" MyAS3App.as -default-size 360 280 -output MyAS3App.swf');
When I run this from the command line, it runs fine and finishes in a second or two.
When I run this command from PHP exec, the java process takes 100% CPU and never returns.
I have also tried running the above command with '/usr/bin/java -Djava.awt.headless=true'.
I am running Mac OS X 10.5.5, MAMP 1.7, PHP 5.2.5
