        Description

        FULL PRODUCT VERSION :
        java version "1.6.0_13"
        Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
        Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)

        ADDITIONAL OS VERSION INFORMATION :
        Microsoft Windows XP [Versione 5.1.2600]

        Microsoft Windows [Version 5.2.3790]

        Linux ws-devel8 2.6.27-11-generic #1 SMP Wed Apr 1 20:57:48 UTC 2009 i686 GNU/Linux

        A DESCRIPTION OF THE PROBLEM :
        With Java 1.6.0_13 if you have an applet run through Java Web Start and you call:

        getAppletContext().showDocument(myURL, "_blank");

        the browser is not launched and the URL is not opened.
        This problem sometimes happens with 1.6.0_12, too, although we have an applet in which this works correctly in 1.6.0_12, but does not work in 1.6.0_13.

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        1. compile the attached code
        2. create a JAR and sign it
        3. create the following JNLP and put it into a web server, together with the JAR, adapting the codebase and jar href attributes values as appropriate:

        <jnlp spec="1.5+" codebase="http://localhost:8080/test/" version="1.0">
          <information>
            <title>Test</title>
            <vendor>Test</vendor>
            <homepage href="http://www.sun.com"/>
          </information>
          <security>
            <all-permissions/>
          </security>
          <update check="timeout" policy="always"/>
          <resources>
            <j2se href="http://java.sun.com/products/autodl/j2se" version="1.6.0_13"/>
            <j2se version="1.6"/>
            <j2se version="1.5"/>
            <jar href="http://localhost:8080/test/test.jar" download="eager" main="false"/>
          </resources>
          <applet-desc name="Test" main-class="test.MyApplet" width="400" height="200">
          </applet-desc>
        </jnlp>

        4. connect to that jnlp using any browser
        5. after the application has started, click on the "click" button

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        A new browser page is opened, pointing to http://www.sun.com

        This happens correctly if you have any of the following tested Java version installed:

        1.5.0_17
        1.6.0_01
        1.6.0_03
        1.6.0_05
        1.6.0_10
        ACTUAL -
        Nothing happens.

        This is always reproducible with 1.6.0_13.

        The attached test case reproduces the problem also with 1.6.0_12. However, we have a production applet in which the described method works correctly with 1.6.0_12, but does not work with 1.6.0_13.

        The problem has been reproduced under Windows XP, Windows XP x64 Edition and Linux Ubuntu 8.10.

        ERROR MESSAGES/STACK TRACES THAT OCCUR :

        REPRODUCIBILITY :
        This bug can be reproduced always.
