Array access replacement generates invalid bytecode when padding is required
----------------------------------------------------------------------------

                 Key: JBAOP-690
                 URL: https://jira.jboss.org/jira/browse/JBAOP-690
             Project: JBoss AOP
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.0.0.SP1, 2.0.0.GA
            Reporter: Jason T. Greene
            Assignee: Jason T. Greene


When using array interception, bytecode verification errors can occur similar to:

 java.lang.VerifyError: (class: com/lm/dataModel/rules/StatusRule, method: propagateFromHereOnUpTree signature: (Lcom/lm/dataModel/ANode;Lcom/lm/dataModel/ANode$Source;Lcom/lm/dataModel/ANode$StatusValue;)Z) Unable to pop operand off an empty stack
     at com.lm.dataModel.ANode.setStatusValueWithPropagation(ANode.java:301)
     at com.lm.seem.StatusTableModel.setValueAt(StatusTableModel.java:133)

The problem lies in javasisst (see linked bug for details).
