563801 - Mouse events not passed to Java applets in Carbon event mode using most recent Java Plugin2

Status: RESOLVED INCOMPLETE

(Plugins Graveyard :: Java (Apple), defect)

Description

[Steven Michaud [:smichaud] (Retired)]

This report is about the Java Plugin2 that comes with Apple's most
recent Developer Previews (Java for Mac OS X 10.5 Update 7 build
9M3150 and Java for Mac OS X 10.6 Update 2 build 10M3050).

As best I can tell, no mouse events are passed to a Java applet unless
the browser supports the NPAPI Cocoa event model.

The current versions of Safari and Minefield do support the Cocoa
event model.  But Firefox 3.6.X and older don't (only the so-called
Carbon event model).

Minefield started supporting the Cocoa event model with the following
nightly (after the patch for bug 435041
http://hg.mozilla.org/mozilla-central/rev/ebb78acb0087 landed):

Here's a good applet to test with:

You should be able to move the molecule around with the left mouse
button.  You should see a context menu when you right-click on the
applet.  The molecule should grow larger or smaller when you scroll the
scroll wheel down or up.

This web-page illustrates the same problem.

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
