Description
URL: http://hs.iwon.com/games/knockemout.html

Problem: When running the GameHouse's Knock Em Out applet in Java Plug-in or appletviewer in Merlin b90 on Win32, the applet loaded and started successfully. However, there is no rendering of the applet. When the applet is covered and uncovered by other window, then the applet is repainted. Since there is animator in the applet, none of the animator is shown on the screen. The problem can also be reproduced using both JPI and appletviewer, so this is likely to be an AWT bug.

To reproduce it in Java Plug-in:
- Install Merlin b90.
- Goto http://hs.iwon.com/games/knockemout.html
- See the applet and the rendering problem.

To reproduce it in appletviewer:
- Install Merlin b90.
- Type the following in the command prompt:

	appletviewer -J-Xbootclasspath/a:<jdk>\jre\lib\jaws.jar -J-DtrustProxy=true -J-Dhttp.proxy=scaweb1.sfbay.sun.com -J-Dhttp.port=8080 http://hs.iwon.com/games/knockemout.html

- See the appletviewer and the rendering problem.


This problem doesn't occur with the 1.3.1_02 appletviewer and Java Plug-in, so this could be a regression.

Comments
EVALUATION Reproducable with appletviewer on Solaris also. ###@###.### 2002-01-22 My inclination is that a panel is being added, but it is not being validated. ###@###.### 2002-01-22 Verified that the canvas is being added, validated then shown. It appears the "showing ad" is disrupting the proper display of the canvas. As I do not have the source code to this applet it is very difficult to sort out what's going on. Marking the bug incomplete with the hope of getting the source code for the applet. ###@###.### 2002-01-23 I was able to test and reproduce using appletviewer.. appletviewer -J-Xbootclasspath/a:D:\jbuilder5\jdk1.3\jre\lib\jaws.jar -J-D"trustProxy=true" -J-D"http.proxy=webcache.sfbay.sun.com" -J-D"http.port=8080" http://hs.iwon.com/games/knockemout.html ###@###.### 2002-01-24 We expect this bug to be fixed by the putback for 4690831: same issue. ###@###.### 2002-06-20
