1.4.2_02 02Fixed

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.

EVALUATION Commit to fix in Tiger. ###@###.### 2003-05-12 The problem is due to an invalid object is being passed to awt_post_java_mouse_event() and subsequently crashes in jni_GetObjectClass. I've attached a native stack trace with line numbers corresponding to 1.4.1_04 in the attachment (native.txt). The fix is to check if the current widget is of AWT type. The cause for this bug is that the fix for 4413973 wasn't forward ported correctly from 1.2.2/1.3 to 1.4/1.4.1/1.4.2. ###@###.### 2003-07-09
