Possible reason - incorrect procession of <applet-desc> tag in jnlp file, since this is the only test with this tag. Attempt to start other appet with jnlp file also failed.

Steps to reproduce the test failure:
1. Install JDK 1.6.0_12 b01 (for example to /export/jdk/jdk1.6.0_12)
2. Enable tracing and logging in Java Control Panel. Enable Show console option.
2. Run command /export/jdk/jdk1.6.0_12/bin/javaws http://stt-13/results/1.6.0_12/b01_j4b/TCK-jnlp/jnlp-x86-OpenSolaris/rerun/test.jnlp
Files needed to run the test are accesible from stt-13.russia from /set/stt/newroot/results/1.6.0_12/b01_j4b/TCK-jnlp/jnlp-x86-OpenSolaris/rerun (or from the link above)
Test suite is installed in /set/stt/tck_promotions/jnlp_tck/6.0/beta/b03/binaries/jnlp_tck60 (accessible also from stt-13.russia)

*.jnlp file could be reduced and ordinary clock applet demo could be used to reproduce problem.
Run command /export/jdk/jdk1.6.0_12/bin/javaws http://stt-13/results/1.6.0_12/b01_j4b/TCK-jnlp/jnlp-x86-OpenSolaris/rerun2/test.jnlp
(file are at /set/stt/newroot/results/1.6.0_12/b01_j4b/TCK-jnlp/jnlp-x86-OpenSolaris/rerun2)

</jnlp>

With JDK 6u11 will see an applet demo and with 6u12 will see a stack trace.

N/A

Problem:  We failed to start JNLP applet if the JNLP file of the applet has no JNLP href

Fix:

1.  Use getCanonicalHome to lookup cached JNLP file, so that no-href JNLP file can be found from cache

2.  If jnlp file has no href, we cannot fetch it again from the network.  use cached copy instead if available.

Its due to a bug fix in 6u12 b01:
6740227 DnD: file associations dont work for dragged out applets

where we did some code refactoring in the launch sequence of JNLP applets.   This caused the failure to start JNLP applet if the JNLP file of the applet has no JNLP href.
