Description

Example plugin configuration (jaxbri databinding):

The properties XtoString, Xequals, XhashCode don't have any values.
Because of the bug you must provide some string values and can't completely omit <value> element like this:

<!-- generate toString methods -->
<property>
<name>XtoString</name>
</property>
<!-- generate equals methods -->
<property>
<name>Xequals</name>
</property>
<!-- generate hashCode methods -->
<property>
<name>XhashCode</name>
</property>

But now it throws the following exception:
