java.lang.VerifyError when trying to run an application; possibly a problem with a class being in other than "default" package.

I'm not entirely sure it's a bug, most likely I'm just doing something wrong, but the FAQ says if I see this error - report it as a bug, so here it goes:

>>>>>>>>>>>>>>>>>>

java.lang.VerifyError: (class: com/riskmetrics/processmanagement/ca/servicedesk/domain/RMGSDOrganization, method: JiBX_RMGSDOrganizationBinding_marshal_1_1 signature: (Lorg/jibx/runtime/impl/MarshallingContext;)V) Incompatible type for getting or setting field

>>>>>>>>>>>>>>>>>>

This is what I'm trying to do:
I have a data xml that looks like this

<?xml version="1.0" encoding="UTF-8"?>
<RMGSDOrganization xmlns="">
<Handle>org:401346</Handle>
<Attributes>
<last_mod DataType="2004">1084823216</last_mod>
<service_type DataType="2005">0</service_type>
<name DataType="2002">3M Company (3)</name>
<delete_flag DataType="2005">0</delete_flag>
<org_num DataType="2002">3</org_num>
<alt_phone DataType="2002"/>
<phone_number DataType="2002"/>
<id DataType="2001">401346</id>
<location DataType="2005">0</location>
<billing_code DataType="2002"/>
<email_addr DataType="2002"/>
<fax_phone DataType="2002"/>
<contact DataType="2005">0</contact>
<alias DataType="2001">-1</alias>
<pemail_addr DataType="2002"/>
<description DataType="2002"/>
<persistent_id DataType="2002">org:401346</persistent_id>
</Attributes>
</RMGSDOrganization>

I have a class RMGSDOrganization to mirror the XML structure. The class is located in the package com.riskmetrics.processmanagement.ca.servicedesk.domain

public class RMGSDOrganization {
private String last_mod;
private String service_type;
private String name;
private String delete_flag;
private String org_num;
private String alt_phone;
private String phone_number;
private String id;
private String location;
private String billing_code;
private String email_addr;
private String fax_phone;
private String contact;
private String alias;
private String pemail_addr;
private String description;
private String persistent_id;
private String handle;
// getters and setters ommited
}

The binding is in the file RMGSDOrganizationBin
ding.xml and looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<binding package="com.riskmetrics.processmanagement.ca.servicedesk.domain">
<mapping name="RMGSDOrganization" class="RMGSDOrganization">
<value name="Handle" field="handle" usage="optional"/>
<structure name="Attributes">
<value name="last_mod" field="last_mod"/>
<value name="service_type" field="service_type"/>
<value name="name" field="name"/>
<value name="delete_flag" field="delete_flag"/>
<value name="org_num" field="org_num"/>
<value name="alt_phone" field="alt_phone"/>
<value name="phone_number" field="phone_number"/>
<value name="id" field="id"/>
<value name="location" field="location"/>
<value name="billing_code" field="billing_code"/>
<value name="email_addr" field="email_addr"/>
<value name="fax_phone" field="fax_phone"/>
<value name="contact" field="contact"/>
<value name="alias" field="alias"/>
<value name="pemail_addr" field="pemail_addr"/>
<value name="description" field="description"/>
<value name="persistent_id" field="persistent_id"/>
</structure>
</mapping>
</binding>

****************************

I compiled the binding
by executing this line from the package location of the class file:

C:\eclipse\plugins\jibx\lib\jibx-bind.jar RMGSDOrganizationBin
ding.xml

The compilation goes on without errors and files JiBX_RMGSDOrganizationBindingFactory.class and JiBX_RMGSDOrganizationBindingRMGSDOrganization_access.class get generated in the package location.

My test driver is TestJibxOtherPackage in the default package.
The error is caused by this line:

IBindingFactory bfact = BindingDirectory.getFactory(com.riskmetrics.processmanagement.ca.servicedesk.domain.RMGSDOrganization.class);

*****************************

NOTE:
If all the files (RMGSDOrganization.class, RMGSDOrganizationBin
ding.xml and the files generated by the binding compilation) are located in the default package, the test runs fine!

The FAQ suggests to specify the package in the binding definition, which I did, but it doesn't seem to fix the problem. I also tried to fully qualify the class name in the mapping definition, but still no luck:

<mapping name="RMGSDOrganization" class="com.riskmetrics.processmanagement.ca.servicedesk.domain.RMGSDOrganization">

Thank you very much,
Oleg.
