dhaniag commented on BEANUTILS-473:
-----------------------------------
When we try to upgrade from 1.7 to 1.9.0 as part of jasper report library found
some features broken.
Test cases
1) Define an Integer variable in Class1
private Integer var1;
2) Define an int variable in Class2
private int var1;
3) Create object of Class1 and then set the var1 as null
4) Using copy properties copy the Class1 to Class2
Getting below error.
Exception in thread "main" java.lang.IllegalArgumentException: Cannot invoke
Class1.setVar1 on bean class 'class Class1' - null - had objects of type
"<null>" but expected signature "int"
Any solution available? Please help.
Very Urgent
> Backward compatibility - copying null values to primitive types
> ---------------------------------------------------------------

> Key: BEANUTILS-473
> URL: https://issues.apache.org/jira/browse/BEANUTILS-473
> Project: Commons BeanUtils
> Issue Type: Bug
> Components: Bean / Property Utils
> Affects Versions: 1.9.2
> Reporter: Sven Raddatz
> Labels: IllegalArgumentException, backwards-compatibility,
> null-values
>
> Copying a NULL value to a primitve property in destination bean (e.g.
> boolean) was silently ignored in BU 1.7.0. In 1.9.2 this is throwing an
> IllegalArgumentException.
> Since converters are not executed when value is null there is no way to
> prevent this behaviour, making it hard to migrate from 1.7.0 to 1.9.2. The
> only way to accomplish this task is to switch from primitive to non-primitive
> types in all destination beans, which would result in huge testing effort.
> It would be nice to either have the possibility to use convertes to handle
> null values with a valid default (e.g. null = false in case of boolean) or to
> globally have a switch for a "silent / lenient mode" where any exceptions
> during copying are silently ignored.
