Migrating from Java 6 (Swing) to 8

[Vindieselwalker]

Hi

I work on a big application, which was coded almost 10 years ago.

It was coded against java 6, and we now think about upgrading to java 8.

Already tried to load everything in Eclipse and compile/launch against JDK 8 (171), almost everything works, but I still have some concerns about java stacks poping on some actions (someone told me it's related to events sequence which could have changed ?).

Also, Eclipse is warning me about restrictions on libraries (ie, sun.awt.CausedFocusEvent.Cause.ACTIVATION, but some others also, ...)

Do you have anny tips for a successfull migration to Java 8 ?

As you can imagine, I'm not an expert, so what warning should I follow ?

Thanks
