Java 9 EA 169 Webstart NoClassDefFoundError: javax/xml/ws/Service

[Reto Merz]

Thanks Alan.

Wouldn't it make sense to add all modules by default in Java 9 in case of Webstart and print
a warning to the Webstart console the first time a future non-default module is accessed
with the message that the JNLP must be extended with a --add-modules=moduleXY in Java 10?

So all the Webstart app devs would get more time to adjust the JNLP to support Java9/10.

Regards
Reto
