Here is a sample code that crash the VM:
import java.dyn.*;
public class Crash {
public static void foo(Object o) { }
public static void main(String[] args) {
MethodHandles.Lookup lookup = MethodHandles.lookup();
MethodHandle mh = lookup.findStatic(Crash.class, "foo",
MethodType.methodType(void.class, Object.class));
for(;;) {
try {
mh.invokeExact("bad arg!");
} catch(WrongMethodTypeException e) {
// do nothing
} catch(Throwable t) {
t.printStackTrace();
}
}
}
}
I try to do an invoke exact with the wrong signature (String instead of
Object),
the VM throws a WrongMethodTypeException. But when the JIT is triggered,
the VM crashs.
