Re: Trident exception in Amber

[Kirill Grouchnikov <kirillcool@yahoo.com>]

Looks like you're using an older Trident version. The TimelineEngine.enqueueTimelineOperation is in lines 1333-1338, and line 1263 is a return statement in resumeTimeline.

Thanks

Subject: Trident exception in Amber

Hey Kirill,

I mentioned i was seeing some weird exceptions with Amber for my recent
effects demo, and your latest changes removed 50% of them, one of the
two :)

Here's the other stacktrace of a NPE, however i don't know if it's
because the trident behavior changed when Amber hasn't. It's all using
the regular Amber code, i had those before adding the decora effects so
hopefully you can reproduce it if need be.

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
