App crashes with error "no such method: sun.awt.image.ImageWatched..." #106

Closed oeway closed 8 months ago

oeway commented 4 years ago

I see this error from time to time, and it cause the entire app to crash:

Uncaught (in promise) no such method: sun.awt.image.ImageWatched$WeakLink.lambda$update$0(ImageObserver,Image,int,int,int,int,int)Boolean/invokeStatic

and error points to line 2268 of the loader.js file (version: 20200927): 

            currentThread.parent.endPromise.fail(detailMessage);

To reproduce the issue:

  1. goto https://ij.imjoy.io/
  2. click "File -> New -> Image...", then click ok in the dialog
  3. now click "File -> Save", then the app crashes and you can see the error in the console.

We expect this problem to be fixed with the new CheerpJ 3.0 architecture. Please let us know if that is not the case.
