Subject [jira] Commented: (HARMONY-1336) [classlib][beans] unexpected IllegalArgumentException for PropertyChangeSupport.fireIndexedPropertyChange(...)
Date Thu, 12 Apr 2007 19:45:15 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12488486
] 

Sandy McArthur commented on HARMONY-1336:
-----------------------------------------

This bug is from "new IndexedPropertyChangeEvent(source, propertyName, oldValue, newValue,
index)" in PropertyChangeSupport.fireIndexedPropertyChange(String propertyName, int index,
Object oldValue, Object newValue). The parameter "source" for IndexedPropertyChangeEvent should
be "sourceBean". The field "source" only ever gets assigned a value when writeObject is called
during serialization. Otherwise "source" is always going to be null.
