Description of problem:
When checking the version of the current Java setup by running

  http://www.java.com/en/download/installed.jsp?detect=jre&try=1 ,

no results is returned, not even after a second attempt after exceeding the time-out of 60 seconds. The following URL

  http://www.java.com/en/download/installed.jsp?detect=jre&try=2

then is superseded by
  
  http://www.java.com/en/download/installed.jsp?jreinit=no ,

and instead of a Java version info an empty text field appears. Only minutes later, the correct info appears in said browser window, namely

Version-Release number of selected component (if applicable):
icedtea-web-1.0.2-2.fc15.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Open http://www.java.com/en/download/installed.jsp?detect=jre&try=1 in firefox.
  
Actual results:
After two failed attempts, the applet calims that no Java is available on the system. Then after a few minutes, the version info eventually shows up.

Expected results:
Version info is returned without delay.

Additional info:
- Other Java applets also take a long time to execute leading the user to believe that Java is not working at all.
- Java appears to be completely unusable whith epiphany.
- This might also be an issue with nspluginwrapper.
