jibx: Missing required object exception

I'm useing JiBX to marshall some Classes. It works well, until i get a IllegalStateException

java.lang.IllegalStateException: Missing required object

The xml output stops at an other (further) position (maybe it get's not flushed):

...         
<objectsmaterial>
            <material>
                <name>
                    <localizedtext size="1">
                        <entry key="de_AT">Furnier Kanadische Ahorn</entry>
                    </localizedtext>
                </name>
                <longtext>
                    <localizedtext size="1">
                        <entry key="de_AT">
[EOF]

Is it a problem with usage="optional" not set? Is JiBX expecting a field with doesn't exist? I'm missing debug output on JiBX but this is already reported as a bug in their JIRA.

if anybody has an idea what's wrong, or how I can find out whats wrong, please!

Here my binding0.xml binding0.xml pastebin

Thanks in advance

The IllegalArgumentException occours if a field is null, if it has (XML-)Subelements.

I doublechecked the code and I found the bug.
