Description

Here is related code:

2581             properties.setProperty(attr, value);
2582             updatingResource.put(attr, source);
2583           } else if (!value.equals(properties.getProperty(attr))) {

The null check in the enclosing if statement is accompanied with allowNullValueProperties, thus dereferencing value above may result in NPE.
