Subject [jira] Commented: (BEANUTILS-349) copyProperties throws NullPointerException if an IllegalArgumentException is thrown due to a null value parameter for a primitive
Date Wed, 07 Oct 2009 15:30:31 GMT

    [ https://issues.apache.org/jira/browse/BEANUTILS-349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12763096#action_12763096
] 

Niall Pemberton commented on BEANUTILS-349:
-------------------------------------------

I found when testing with JDK 1.3 and 1.4 that Method.invoke() throws a NullPointerException
if a value is null for a primitive parameter (whereas JDK 1.5+ throws an IllegalArgumentException)
- so I have made an additional change so that BeanUtils works the same way whatever the JDK
version:

> When using copyProperties from a bean with a Boolean field to a bean with a corresponding
boolean field (i.e. a primitive), an IllegalArgumentException is thrown when calling method.invoke.
 invokeMethod tries to format a user friendly exception string, but fails to check if the
value parameter is null before getting it's classname.
