Hi Sushmita, please also upload your example file otherwise we can't validate/fix this issue. Andi Created attachment 36517 [details]
Issue related to ClassCastException which we are facing while using poi-4.0.1 along with java 11
Code causing classcastexception:
CustomProperty property = (CustomProperty) e.getValue();
CustomProperties newCustomProperties = dsi.getCustomProperties();
Iterator iterator = customProperties.entrySet().iterator();
while (iterator.hasNext())
{
Map.Entry e = (Map.Entry) iterator.next();
CustomProperty property = (CustomProperty) e.getValue();
String name = property.getName();
Object oldValue = property.getValue();
}
hi Andrea, Could you please provide us information on the same ? Regards, Sushmita Sushmita - where does the code from your comment of 2019-04-10 09:43:14 UTC come from? If it is your code, then you shouldn't be doing a class cast. You should check if the value is an instanceof CustomProperty before casting it. From the JavaDoc of CustomProperties: While this class is roughly HashMap<Long,CustomProperty>, that's the internal representation. To external calls, it should appear as HashMap<String,Object> mapping between Names and Custom Property Values. I think, this is enough explaining the error - I'm closing this now as "invalid". |
