JVM crashes when executing a class which tries to load
two classes via Class.forName: sun.awt.motif.MPanelPeer and sun.awt.X11SurfaceData.
See below how to reproduce.
This occurs with JDK1.4.0beta-b80, 81, 82 (other builds not checked).
Machine (output of uname -a command):
SunOS novo86 5.8 Generic_108528-07 sun4u sparc SUNW,Ultra-2

To reproduce:

1. Compile the source file a.java:

<JDK1.4>/solsparc/bin/javac a.java

--- a.java ---
public class a {
public static void main(String[] args) {
Class c;
try {
c = Class.forName("sun.awt.motif.MPanelPeer");
c = Class.forName("sun.awt.X11SurfaceData");
} catch (Throwable e) {
}
}
}
--- end of a.java ---

2. Run class a:

<JDK1.4>/solsparc/bin/java -cp . a

JVM output:
An unexpected exception has been detected in native code outside the VM.
