The Hotspot VM (build 1.4.1-beta-b18) fails the following test
from testbase_nsk:

    nsk/jvmdi/RedefineClasses/redefclass011

The test exercises JVMDI function RedefineClasses(classCount, classDefs).
The test checks if the function returns JVMDI_ERROR_INVALID_CLASS
if classDefs[].clazz field is null.

The test is based on the following assertion from JVMDI spec:

| Redefine Classes
|
| typedef struct {
| jclass clazz; /* Class to be redefined */
| jint class_byte_count; /* number of bytes defining class (below) */
| jbyte *class_bytes; /* bytes defining class */
| /* (in Class File Format of JVM spec) */
| } JVMDI_class_definition;
|
| jvmdiError
| RedefineClasses(jint classCount, JVMDI_class_definition *classDefs)
|
| ... (skipped)
|
| This function returns either a universal error or one of the following errors:
|
| JVMDI_ERROR_NULL_POINTER
| Invalid pointer: classDefs or one of class_bytes is NULL.
|
| JVMDI_ERROR_INVALID_CLASS
| An element of classDefs is not a valid class.

To reproduce the bug run script in GammaBase/Bugs/<this bug number> directory:

    sh doit.sh <JAVA_HOME>

Running the test outputs:

java version "1.4.1-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-rc-b18)
Java HotSpot(TM) Client VM (build 1.4.1-rc-b18, mixed mode)
Error expected: JVMDI_ERROR_INVALID_CLASS,
        actual: JVMDI_ERROR_NULL_POINTER (100)
