Body:
I also get the NPE when compiling my binding.
The is a backwards reference, both in the mapping file and in the XML document.
I tried adding forward="false" to the jibx-binding root element, but I still got the
NPE.
The following binding (with much snipped)
<mapping name="HardwareInstallation"
class="edu.iris.dmc.isis.HardwareInstallation" >
<structure name="dbInfo" >
<value name="uid" field="uid" ident="def" />
</structure>
[snip]
</mapping>
<mapping name="StationConfiguration"
class="edu.iris.dmc.isis.StationConfiguration" >
[snip]
<collection name="InstalledItems"
add-method="addHardwareInstallation"
iter-method="getInstalledHardwareIterator" >
<value name="Installation"
type="edu.iris.dmc.isis.HardwareInstallation"
ident="ref" />
</collection>
[snip]
</mapping>
And I get a NPE when I try to compile the binding.
(from runtime binding:)

Description:
java.lang.NullPointerException

occurs with the following binding excerpt:
<mapping name="form" class="com.livis.xforms.desc.Form">
<collection name="constraints" field="constraints"/>
<value name="typeref" field="typeref" usage="optional"/>
<collection field="constraintrefs">
<value name="constraint-ref" type="com.livis.xforms.desc.Type" ident="ref"/>
</collection>
<structure field="layout" usage="optional"/>
</mapping>
<mapping name="type" class="com.livis.xforms.desc.Type">
<value name="name" field="name" ident="def" style="attribute"/>
</mapping>
...
This makes it impossible to unmarshall a list of pointers.
