...and then wait a year or longer until the fix is delivered with the 
next major java release.
Sorry, this is not really a viable option. Besides we still use 
webstart, so forking the jdk is not an option either.

Wouldn't it be better to allow developers to override methods at their 
own risk.
So, instead of making methods final, add a special annotation like 
@DoNotOverride to methods, which are not intended to be overridden by 
the designer of the framework.
The compiler can emit warnings, if the developer decides to override the 
method anyway.

This would clearly indicate to the developer, that his change is 
dangerous and he can not count on support from oracle, if his 
application breaks.

Yet, those that are willing to take the risks, can do something to keep 
their business alive.
