Description

Name: pa48320			Date: 08/19/2003

Create a C++ program on windows that uses sun.awt.windows.WToolKit.embeddedInit() and has an EmbeddedFrame with a child of java.awt.Panel. Disposing the frame causes messages to be posted instead of sent (PostMessage instead of SendMessage) which means that the destructino of the window can happen before the messages to dispose the java objects can happen first. A zip file with a preproducing MS Devstudio project will be attached.

EVALUATION Commit to fix in Tiger. ###@###.### 2003-08-19 Name: ssR10077 Date: 08/22/2003 ###@###.### 2003-08-22 The problem is we receive WM_DESTROY due to disposal of EmbeddedFrame parent window. Our handler in AwtComponent does `delete this;` so after WM_AWT_DISPOSE is handled second delete crashes. ======================================================================
