OpenJ9-8u432 crashes when loading awt_xawt library #23048
Description
Description
When I use the OpenJ9 JDK 8u432 and attempt to load the standard AWT native library (awt_xawt), the JVM unexpectedly crashes with a segmentation fault. This indicates a severe memory access error in the OpenJ9 native runtime when initializing AWT dependencies.
Version Information
jdk8u432-b06
Program
public class LoadAwt {
public static void main(String[] args) {
System.loadLibrary("awt_xawt");
}
}
Actual Behavior
Unhandled exception

Expected Behavior
JVM should successfully load the awt_xawt library and exit cleanly, demonstrating AWT native stability in this build.
