[jira] [Commented] (BEANUTILS-464) NullPointerException in PropertyUtilsBean.invokeMethod()

["Ralf Hauser (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEANUTILS-464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14071720#comment-14071720 ] 

Ralf Hauser commented on BEANUTILS-464:
---------------------------------------

The javadoc says: 'Copy property values from the "origin" bean to the "destination" bean for all cases where the property names are the same'

It doesn't say that there will be a null-pointer for the properties that are not present in the origin.

in the v1.9.1 the problem was still there on line 2167
