Local fix

• a) If you open the cache viewer with javaws -viewer then select
  the locally cached JNLP and press "run online", then it is
  downloading and executing the new JNLP from the server.
  b) When you clear the cache and run the tests, it works fine
  

Problem summary

• Even if newer files are available, the resources were not
  getting updated and the version from cached was being used to
  launch the javaws. This was introduced through oracle bug-id
  <8098826>. This is fixed in reference implementation through
  <8141527> but was not ported into IBM JDK.
  

Problem conclusion

• Fix implemented in oracle bug <8141527> has been ported to IBM
  JRE and the application now picks the latest jnlp files when it
  identifies any change
  .
  This APAR will be fixed in the following Java Releases:
     8    SR5 FP15  (8.0.5.15)
     7    SR10 FP25 (7.0.10.25)
  .

  Refreshes and Fix Packs.
