Tested bundle: jdk7 b127-pit. http://rehudson.sfbay.sun.com/hudsonws/deploypit/bundles/windows-i586/b255-2011-01-20_29/
Tested OS: winxp
Tested browser: firefox 3.6

Steps to reproduce:
I tried the 2 cases in http://web-east.east/deployment/www/tests/1.7.0/7012115/testcase.html with b127-pit bundle on xp

For the first case,
I found sometimes, it is decorated, I think it should be the expected behavior, because in spec(http://j2se.sfbay.sun.com/web/bin/view/Deployment/DecoratedParam) ,it says the default behavior for jnlp applet is: an applet launched via the applet-desc will have "decorated" frame.
Then I modified the jnlp, specify the decorated=false in jnlp file. Please look at this html(http://rehte.cn.oracle.com:8080/wshost/tmp/test_decorated.html). When I dragged out the applet, I found it is also decorated which is not expected.

For the second case,
Seems it is still undecorated
Add 2 more cases which have <param name="decorated" value="true" /> parameter, but the dragged out applet's frame is undecorated
