(Note: don't know which version of NSPR to assign this to - this happened after doing a complete install of Netscape Seamonkey from Dec 14, 99). Go to Netcenter (home.netscape.com) click on "Play Online" in the Games channel click on "Hearts" (where you might have to sign-in or sign-up) click a "Casual Lodge" so you can play hearts. This is supposed to launch a window and run a java applet. Instead, after launching the window, you get the following "java warning" from Netcenter. The following error has occurred: Java Warning Explanation: Unfortunately, the Web browser you're currently using either doesn't support Java or you have Java (or Javascript) disabled in your browser. You must have a Java-enabled browser to play the Classic Games. If you don't have Netscape Navigator 3.x, Netscape Communicator 4.x or Microsoft Internet Explorer 4.x, you can download the latest versions from the sites below:

What is bug the NSPR bug that is causing this problem?

There is no information relevant to NSPR; re-assigning the bug to johng

This is a java question - don't know which engineer owns this problem. Reassigning to Eric Krock.

Change component from "NSPR" to "Browser"

DUP #23672. Known bug. Java doesn't work post-M12 right now. *** This bug has been marked as a duplicate of 23672 ***

Marking Verified as a dup.

Reopened since still a problem even though this bug's duplicate, bug 23672, was fixed. Beta 1 build # 2000032719, Netcenter java games still don't work. Never has.

Java broken-->nsbeta2. Java on b2 list. Reassigning to drapeau@eng.sun.com. John: thanks for reopening! But don't assign Java bugs to me; assign them to the OJI component or to drapeau@eng.sun.com if you have to specify an individual, so that engineering has them.

Putting on [nsbeta2+] radar for beta2 fix.

Adding netcenter keyword to make them aware of issue.

I'm curious as to when this gets resolved. Adding myself CC:

The problem still exists Tried on Mozilla build M16 milestone and nightly 07/12/2000 on WiNNT SP5 and Java Plugin version 1.3.0-netscape-pr2 Also since I'm going thru' a proxy, maybe it does not allow it to load the applet ( prompts a 'unable to connect' error in IE5 when trying to load the game. )

I'm finding that there's a java error here as well. This may be due to the old SetWindow(), Stop() thing happening in the wrong order. I'm re-assigning to Stanley to take a look.

Yes, the error is caused by the fact that SetWindow(), Init(), Start(), Stop(), Destroy() are called in the wrong order.

No one seems to be looking at this bug. cc'ing ekrock and jar.

It's a Java backward compatibility bug. I do hope that Sun (or someone else) has the time to fix this, but that will have to be a call they make. cc:ing chrisn who has Netcenter contacts and drapeau to get this on manager triage radar.

This bug looks like it could be part of a larger problem, which is race conditions between Mozilla and the JVM. The lifecycle of applets (perhaps plugins in general; we don't know yet for sure) is messed up, so that often the plugin host (i.e., the browser) will destroy a parent window before an applet can clean up after itself. This results in "null pData" messages from the JVM, the "pData" (a private data structure pointing to native windows, etc.) being the window that the plugin host just destroyed. We're working on a general fix for this lifecycle problem. We're trying to find workarounds in the Java Plug-In, and also trying to find the right way to fix this in the Mozilla code. When that's done, we'll re-evaluate this and a number of other related bugs to see if they go away. If they do, excellent. If not, we'll work on this separately.

Taking Stanley's word and marking this as a dup of bug 50547. *** This bug has been marked as a duplicate of 50547 ***
