ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
In JavaObjectArray.resolve, there is code to attempt to handle the case where the class object for the class of the array cannot be found.

        if (clazz == null) {
clazz = snapshot.getOtherArrayType();
        }

However, this does not work because fiels clazz is never null - it contains a Number which is the id of the class object we are looking for. JHAT then crashes when it tries to cast the Number to a JavaClass.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
The followint change seems to work:
original:
    public void resolve(Snapshot snapshot) {
        long classID = getIdValue((Number)clazz);
        if (snapshot.isNewStyleArrayClass()) {
replacement:
    public void resolve(Snapshot snapshot) {
        long classID = getIdValue((Number)clazz);
        clazz=null; // add this line
        if (snapshot.isNewStyleArrayClass()) {
