The following problem was discovered by running JCK under hotspot on Solaris.
Test "JCK-runtime-api-12a/api/javax_swing/text/DefaultEditorKit/index_SubCtors"
fails when trying to test the effect of a CutAction, call the native method
"Java_sun_awt_motif_X11Selection_registerTargetForFlavor", and triggers an
assert (or a core dump, if VM asserts are disabled).

The following line of code in awt_Selection.c is at fault:
    (*env)->SetIntField(env, flavor, x11SelectionIDs.atom, (jint) target);

The problem is that "flavor" is not of class X11Selection. It is a method
argument, not the method invocation target "this", and it is of class
DataFlavor. Although it does have a field named "atom", it is not the
same field as in X11Selection, and in fact is at a different offset.

This bug appears to be an erroneous fix to a larger bug, number 4107322.
This bug may be fixed by correctly applying the techniques described in
the bugtraq entry for 4107322.
