FULL PRODUCT VERSION :
java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux impala 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux


EXTRA RELEVANT SYSTEM CONFIGURATION :
This problem is almost certainly platform independent.

A DESCRIPTION OF THE PROBLEM :
The following .jnlp file can be started using the javaws included in the Java runtime 1.6.0_29, but *cannot* be started using the javaws included in the Java runtime 1.7.0_01.

It seems that specifying several, ``large'', <property> elements now poses a problem.

REGRESSION. Last worked in version 6u29

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
[1] Open the following page in a web browser associating .jnlp files to the javaws executable included in the 1.7.0_01 runtime.

http://www.pixware.fr/_download/JWS_BUG/index.html

[2] Click the "Show System Properties" button to start a trivial application displaying all the system properties in a JFrame containing a JTextArea.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You should see a window displaying all the system properties.
ACTUAL -
You get a error dialog box saying "Unable to launch the application".

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Clicking the "Details" button gives:

InvalidArgumentException[ Invalid arguments supplied: { }]
at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Thread.java:722)


REPRODUCIBILITY :
This bug can be reproduced always.

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
When possible,

* remove some <property> elements from the .jnlp

* remove as much value data as possible from the remaining <property> elements.

For example, the .jnlp file used to reproduce the problem can be started if you remove all the <property> elements but one.
