Subject [classlib][awt] Test failure
Date Thu, 23 Nov 2006 17:31:57 GMT
It looks like the following code (taken from [1]) doesn't allow for a
function address not being found.

int (* p_nbridge_XmuLookupStandardColormap) (void *, int, long, int,
long, int, int) = NULL;

JNIEnv *env, jobject self, jlong dpy, jint screen, jlong visualid, jint
depth, jlong property, jint replace, jint retain) {
    if (p_nbridge_XmuLookupStandardColormap == NULL) {
        p_nbridge_XmuLookupStandardColormap = (int (*) (void *, int,
long, int, long, int, int)) FindFunction(libXmu,
    return (jint) (* p_nbridge_XmuLookupStandardColormap)((void *) dpy,
(int) screen, (long) visualid, (int) depth, (long) property, (int)
replace, (int) retain);

which I'm guessing is the cause of the recurrent build failure on the
build machine (latest classlib + IBM VM) ...

Not sure what has changed to cause this failure.  The file [1] says
/* DO NOT EDIT THIS FILE - it is based on X11 headers and was
autogenerated by nativebridge tool */

so I'm guessing I can't fix it up there.  suggestions?
