我有一个具有层次结构的 Maven 多模块项目：
parent
+ ota-module
+ ota-common
+ ota-veh-avail-rate
OTA2003B ( http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B ) 我正在使用的模式：
Common:
OTA_CommonPrefs.xsd
OTA_CommonTypes.xsd
OTA_SimpleTypes.xsd
OTA_VehicleCommonTypes.xsd
VehAvailRate
OTA_VehAvailRateRQ.xsd
OTA_VehAvailRateRS.xsd

com.poc.multimodule.ota.common.ActionType是由 ota-common 模块生成的类型，存在于我正在使用的生成的 base- binding.xml 中。它是 OTA_SimpleTypes.xsd 架构的一部分
架构文件中的ActionType定义
<xs:simpleType name="ActionType">
<xs:restriction base="xs:string">
<xs:enumeration value="Add-Update"/>
<xs:enumeration value="Cancel"/>
<xs:enumeration value="Delete"/>
</xs:restriction>
</xs:simpleType>
是什么导致了这个 java.lang.IllegalStateException: Internal error - cannot modify class 以及如何解决这个问题？
谢谢，
吉涅什
