I am trying to get the JDK 1.2/non-com sources to work on the digital alpha. I tried to run an IDE called super mojo
via
export CLASSPATH=classes:working:temp:.:lib/classes
sh -x java_g -Xverify:none supermojo.Client

Eventually it gets this interesting error. Interesting is that is I dont use java_g
then supermojo gets beyond this point.

FATAL ERROR in native method: Wrong field ID passed to JNI
        at sun.awt.motif.X11Selection.registerTargetForFlavor(Native Method)
        at sun.awt.motif.X11Selection.<clinit>(X11Selection.java:49)

        at supermojo.Client.<init>(Client.java)
        at supermojo.Client.main(Client.java)
SIGABRT   6*   abort (generated by abort(3) routine)

  From what i can observe from the source, the check in check_jni.c
#define CHECK_INSTANCE_FIELD_ID(env, fb, obj)     if (1) {         ValidateObject(env, obj);         if ((fb->access & ACC_STATIC) ||             !is_subclass_of(obj_classblock(DeRef(env, obj)),                            (fb)->clazz, JNIEnv2EE(env)))             UNCHECKED()->FatalError(env, instance_field_msg);     } else ((void) 0)


the is_subclass_of() failes where the classes do not match, even with that of its parents
