[Bug classpath/23028] New: JNI bug causes assertion failure

[pinskia at gcc dot gnu dot org]

With Classpath 0.16, trying to run a very simple Swing demo under JCVM,

I get a JNI assertion failure in a call to GetIntField(), because the object

type and the fieldID are not compatible:



   gnu/java/awt/peer/gtk/address@hidden not instance of 
gnu/java/awt/peer/gtk/GtkGenericPeer



Here is the relevant stack trace snippet:

I think this has been fixed already.
