Axis2生成ArrayStoreException

Question

在以下代碼段中將XML解析為Java類時遇到了ArrayStoreException：

757        StringReader in = new StringReader( xmlString );
758        XMLStreamReader reader = StAXUtils.createXMLStreamReader( in );
759
760        try
761        {
762          ManageContentRequest.Factory.parse( reader );
763        }
764        catch ( Exception e )
765        {
766          this.log.error( xmlString );
767          this.log.info( e.getLocalizedMessage(), e );
768          e.printStackTrace();
769        }

stacktrace是（**前綴行與上面的代碼段匹配）：

通過wsdl和xsd文件，我在Java 1.6.0_24，Windows 7、64位上使用Axis2 v1.6.1生成了Java類。 xsd的相關部分以**前綴突出顯示。

我看了org.apache.axis2.databinding.utils.ConverterUtil的源代碼，以了解那里發生了什么。 上面的代碼段被執行了數百次（> 500）。 我強烈懷疑以前曾調用過ConverterUtil.convertToArray。

有什么想法嗎？

        <tns:Description>You will require this certificate if you are the original breeder of a new variety of plant or if you are acquiring ownership rights from an original breeder.
This certificate will provide exclusive commercial rights to the new plant variety. It provide rights to exclude others from producing propagating material, conditioning propagating material (including cleaning, coating, sorting, packaging and grading), offering propagating material for sale, importing and exporting and stocking propagating material of protected varieties. 

Please consult the Contact Officer for further details.</tns:Description>
        <tns:EligibilityRequirements>As the applicant you must: 

- be the original breeder or have acquired legal ownership; 
- demonstrate that the plant variety is new or recently exploited and is unique (distinct, uniform, stable); and
- have an acceptable name; and
- pay the required fees.

A recently exploited variety is one which had been sold with the breeder's consent in either:

- Australia - not more than 12 months prior to lodging the application; or 
- not more than 6 years (trees and vines) or 4 years (all other species) in another country which is a member of the International Union for the Protection of New Varieties of Plants.

In order to demonstrate that the plant is distinct, uniform and stable (DUS), the applicant will be required to nominate an accredited Qualified Person (QP) as part of the application process. This person will be responsible for conducting a comparative growing trial in order to demonstrate the DUS of the plant.

此后，我已經解決了這個問題。 問題的根本原因是我的數據不正確。 引起問題的URI包含重音符號（`）。 這導致拋出MalformedURIException，但將其忽略。 它甚至沒有被記錄。
