After upgrading to Java 8u202 we are not able to launch our jnlp application.
The only workaround is to clear the java cache and it will launch for only
one time and from second time onward it does not launch again. If we disable
the option to "Keep temporarily files on this computer" option then it does
not reproduce but the problem is every time we launch jnlp file it takes time
to load all the client jars and start.

Looks like there is some problem with Java 8u202 launching java-webstart
applications(JNLP) with java cache enabled. The exception we see when the
application fails to launch is:

ExitException[ 3]java.io.IOException: Server returned HTTP response code: 403
for URL: http://<URL>.jnlp

Please look into this issue asap as our end customers are not able to launch
our product.
