This isn't a bug in the JEP.

But as of the 2007-10-10 trunk nightlies (both Minefield and Camino),
attempting to load _any_ Java applet produces the results described in
comment #0.  The 2007-10-09 trunk nightlies don't have this problem.

This is very likely fallout from the patch for bug 393928.

Comment 2

[Steven Michaud [:smichaud] (Retired)]

The beta shouldn't ship with Java broken on Mac OS X.

Comment 3

[Josh Aas]

Looks to me like the patch on bug 393928 hasn't landed yet.

Comment 4

[Steven Michaud [:smichaud] (Retired)]

Yes it did:

This is not any better on Windows or Linux.  JAVA is mostly broken since the patch for bug 393928 landed.

Comment 6

[Bill Gianopoulos [:WG9s]]

Setting back to mac os x only.  My testing was flawed.  Actually this testcase does work under Windows and Linux.  I have others that fail under windoes and Linux though.

Comment 7

[Steven Michaud [:smichaud] (Retired)]

This bug seems to have been fixed by the fix for bug 399406.

This bug's URL now loads fine, as do simple applets like the following
that I know don't use LiveConnect:

http://java.sun.com/applets/jdk/1.4/demo/applets/Clock/example1.html

So also does a very complex test of applet and non-applet LiveConnect:

http://poslfit.homeip.net/test/liveconnecttest.html

I'll do my best to keep an eye on things.  But for now everything
seems to be fine.

Comment 8

[Steven Michaud [:smichaud] (Retired)]

The fix for bug 399406 (and for this bug) isn't available in today's
trunk nightlies.  But it should be available in tomorrow's.

I'm having problems on http://www.v-workshops.com/java/; I have to click on the middle of the page in order for the applet to appear.  Firefox 2.0.0.8 loads that just fine.  Sadly, Nintendo8.com is down, but you're right, Steven, all the other sites seem to be working fine for me; maybe this is a new bug.

This WORKSFORME with current trunk under both Windows and Linux.

On both Minefield Mac and Camino trunk build, this is indeed the case. Probably better to file a new bug on that.

Comment 12

Still happening on the original URL; reopening.

Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.9a9pre) Gecko/2007102204 Minefield/3.0a9pre on http://www.nintendo8.com/game/314/super_mario_brothers_3/

Once you click the applet, Minefield "hangs"--stops responding to mouse/keyboard events--but doesn't enter the "Not Responding" state, according to the OS.

Comment 13

[Steven Michaud [:smichaud] (Retired)]

Stephen, I can reproduce the problems you report in comment #12.  And
I've found that they happen only on the trunk, and appear to have been
caused by the patch for bug 393928.  But it's no longer the case that
all Java applets have the same problem (and that the JEP is entirely
disabled).

Your original report (though it concerns the same URL and was
literally true) was seriously inaccurate -- because you didn't notice
that all Java applets were effected.  So this bug is now about that
problem.  Please open a new bug on the problem you've reported in
comment #12.

And after you open the new bug, please keep an eye out for other Java
applets that have the same problem.  I currently only know of the one,
so I have no idea how serious this problem really is.

Comment 14

[Steven Michaud [:smichaud] (Retired)]

I should add that the problems you describe in comment #12 only happen
when this bug's URL is the first applet you load (in your browser
session) -- that's why I didn't notice earlier the continuing problems
with this bug's URL.

Here's hoping that bug 401053 is accurately filed this time.

I spun this off as bug 401064.

Since bug 401053 is verified, this is too.
