Java 7 Update 21 and Web Start Install Java Extension problem

1007847
    Hi,

    We've been running WebStart with Java 7 update 17 for several months. Late last month we updated to Java 7 update 21. Since this update, we're seeing 14 additional dialogs when the application is launched. Dialogs are Install Java Exception, do you want to install the following software? and then lists a jar file. I've verified that all JAR and JNLP files are signed with a trusted CA.

    Has anyone else seen this? Is there away to suppress these additional dialogs?

    Thanks,

    Terry
