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

> NullPointerException in PropertyUtilsBean.invokeMethod()
