This is caused by the parameter "paramInt" being unavailable. This parameter is defined in a jnlp file, reference in the HTML as such:
<applet code="AppletTakesParams.class" archive="examples/dist/applet_AppletWithParameters/applet_AppletWithParameters.jar" height="50" width="800"><param name="jnlp_href" value="examples/dist/applet_AppletWithParameters/applettakesparams.jnlp">....</applet>

Hello,

I have made some modification in regards to this issue, I had originally
thought of placing the parsing inside the PluginAppletViewer part of the
code, however it would be better if I kept the jnlp stuff within netx. I
took a sneak peek at your patch and decided that placing it in the
PluginBridge(...) section was a good idea, however I did not think the
other changes were necessary. I have changed it to do this much less
complicated. Here is the attached patch I would like to propose.

ps. Thanks to Omair's patch for idea.

Heh. I am not going to deny that the patch was complex :). It probably
has a number of issues. It's why I didnt post it for review.

However, it implemented much more of the applet-jnlp support. Take a
look at
http://download.oracle.com/javase/tutorial/deployment/deploymentInDepth/runAppletFunction.html
to find out all the different cases where values supplied by the applet
are supposed to be ignore/overwritten by values from the jnlp file.

Updated patch

This is an updated patch which will allow the user to specify parameters
in JNLP files and use it for their applets.

Please let me know if I had missed anything, I've posted it for review
at http://mail.openjdk.java.net/pipermail/distro-pkg-
dev/2011-June/014608.html

Title:
  Openjdk + icedtea6 plugin fails to load parameters from jnlp files

Status in OpenJDK:
  Fix Released
Status in “openjdk-6” package in Ubuntu:
  Triaged

Bug description:
  I was testing applets in the tutorials, this one doesn't work:
  http://java.sun.com/docs/books/tutorial/deployment/applet/param.html (scroll down for applet)

  When launching firefox from console, an error is reported:
  java.lang.NumberFormatException: null
  	at java.lang.Integer.parseInt(Integer.java:443)
  	at java.lang.Integer.parseInt(Integer.java:514)
  	at AppletTakesParams.init(AppletTakesParams.java:39)
  	at sun.applet.AppletPanel.run(AppletPanel.java:436)
  	at java.lang.Thread.run(Thread.java:636)

  This is caused by the parameter "paramInt" being unavailable. This parameter is defined in a jnlp file, reference in the HTML as such:
  <applet code="AppletTakesParams.class" archive="examples/dist/applet_AppletWithParameters/applet_AppletWithParameters.jar" height="50" width="800"><param name="jnlp_href" value="examples/dist/applet_AppletWithParameters/applettakesparams.jnlp">....</applet>
