NullPointerException in BeanUtilsBean .setProperty(), line: 930
---------------------------------------------------------------
Key: BEANUTILS-368
URL: https://issues.apache.org/jira/browse/BEANUTILS-368
Project: Commons BeanUtils
Issue Type: Bug
Components: Bean / Property Utils
Affects Versions: 1.8.1
Environment: JDK 1.6
Reporter: Peter Fassev
Priority: Critical
There is a NullPointerException in the method BeanUtilsBeans.setProperty(Object
bean, String name, Object value) method:
java.lang.NullPointerException
at
org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:930)
The problem is, that few rows earlear the target may be null:
target = getPropertyUtils().getProperty(target,
resolver.next(name)); // NOTE, the result may be NULL.
In such case, the condition at line 930
} else if (target.getClass().isArray() && index >= 0) {
will race a NullPointerException. In the old 1.7.0 version there has been no
such condition or has been executed later...
Proposed FIX: Please add at new line, which checks the "target"
target = getPropertyUtils().getProperty(target, resolver.next(name));
// NOTE, the result may be NULL.
if (target == null) {
return;
}
NOTE. Such check may be added also to the other similar methods, like
BeanUtilsBean.copyProperty().
Regards
Peter
