Some users are facing issues the with native integration: there does
not seem to be any way to disable Sun's mechanism when using WebStart.
Setting the following has no effect:
<property name="sun.awt.disableMixing" value="true"/>
and it is not a secure property so I guess it is set too late for the
effect to occur (it is not part of the properties mentioned here:
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#resources
)
