发送无效的xml时如何修复websphere上的java堆空间

当我向websphere服务器上的web服务发送无效的xml时,我得到了 java堆空间：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/">
   <soap:Header/>
   <soap:Body>
       <MyElementsomething</MyElement>

   </soap:Body>
</soap:Envelope>

与元素

<MyElement>something</MyElement>

一切正常

例外：

编辑：

谁也不知道？

PS：弹簧验证没有帮助,因为它是在websphere之后.当我发送无效的xml agains xsd(例如字符串而不是数字)然后它工作：

2015-02-18 10:12:46.128 [WebContainer : 8] WARN  cz.isvs.ais3.ws.interceptor.ServerPayloadValidatingInterceptor - XML validation error on request: cvc-datatype-valid.1.2.1: 'b' is not a valid value for 'integer'.
2015-02-18 10:12:46.128 [WebContainer : 8] WARN  cz.isvs.ais3.ws.interceptor.ServerPayloadValidatingInterceptor - XML validation error on request: cvc-type.3.1.3: The value 'b' of element 'urn1:Ais' is not valid.

因为WebServiceMessageReceiverObjectSupport.class：

86            WebServiceMessage request = connection.receive(getMessageFactory()); // here occurs out of memory
87            MessageContext messageContext = new DefaultMessageContext(request,getMessageFactory());
88            receiver.receive(messageContext); // and in this method are interceptor which validate request

PS2：

当我尝试将堆空间从2gb增加到4gb时,同一位置还有另一个异常：

java.lang.IndexOutOfBoundsException
        at java.io.PushbackInputStream.read(PushbackInputStream.java:181) ~[?:1.7.0]
        at java.io.FilterInputStream.read(FilterInputStream.java:133) ~[?:1.7.0]

        at com.ibm.ws.webservices.utils.BAIS.create(BAIS.java:77) ~[com.ibm.ws.runtime.jar:?]

PS3：

这是sun java的正确行为：

Caused by: org.xml.sax.SAXParseException: The element type "urn:ZadostInfo" must be terminated by the matching end-tag "</urn:ZadostInfo>".

最好的方法是使用spring payloadinterceptor来对XML模式验证传入的xml,然后才允许进一步解析…
示例代码：

bean id="validatingInterceptor"
    class="org.springframework.ws.soap.server.endpoint.interceptor.PayloadValidatingInterceptor">
<property name="schema" value="/WEB-INF/conf/MyElement.xsd"/>
<property name="validateRequest" value="true"/>
<property name="validateResponse" value="false"/>
