Sorry for the Proguard specific question (is there a Proguard forum?) but it
is JAVA related so I do hope someone can help.

Basically Progaurd is zapping (omitting, treating as surplus) all of my
Applet methods that aren't overriding init(),start(),stop(),destroy() etc.
I'm off to look at the help for the aggressiveness-throttle but does someone
here know how to tell Proguard to back-off in these cases?

I was really impresses when the new JAR file was two-thirds the size of the
original but if it takes out all the good bits then it's far less impressive
:-)

PS. My Applet also implements an Interface which Proguard honours.

PPS. These methods are there to be scripted by Javascript. I'm guessing
there must be a "keep" method just like the keep Applets one?

ProGuard by itself only looks at what seems to be used. It can not see
what some JS may call.

So you need to use the keep* switches.

PS: ProGuard questions here seems quite on topic to me.
