Description
When  running JDK8 or JDK9 deploy code with jre below 7u21, calls to toolkis's abstract method showFileChooser fail with AbstractMethodException.
Before 7u21 the call had 4 args, and after it has 5.
We should catch this exception and try to do something (like calling the 4 arg version thru reflection).

you can see this behavior by installing JDK9 and 7u10 and running :

Verified that this can easily be fixed by changing com.sun.deploy.uitoolkit.ui.UIFactory. instead of having one abstract 5 arg version of showFileChooser, we have two methods. one 5 arg and one 4 arg. The 5 arg version calls the 4 arg version, but is overridden in awt toolkit or FX toolkit from 7u21 on. The 4 arg version is just a dummy, but is overridden in FX pre-7u21 (which is the only time it is actually called).
