JVM crash when dragging from Java UI component to natively rendered window/peer

An ISV uses the techniques outlined in http://java.sun.com/j2se/1.3/docs/guide/awt/AWT_Native_Interface.html for rendering to a Java window via Native Code. The native code rendering is OpenGL-based, and JNI is used for Java - native integration.

When the mouse is dragged from a Java UI component (e.g., Swing, AWT) to the native window with native code rendering, the JVM crashes immediately in 1.4.x (1.4.1_01-b01, 1.4.1_02-b06, 1.4.2-beta-b19). Note that the problem does not occur in 1.3.1_07/_08.

The problem has variously been present (and fixed/absent) since 1.2.x.

This problem was first reported in bug id #4413973, and the fix incorporated for that bug was reportedly included in the 1.4.x tree; however that fix does not address this problem.
