请问，我发布一个bpel应用的时候,总是报错Latch error是怎么回事啊？谢谢。5

Latch error, was releasing for state 1 but actually in -1
我的Test.bpel文件代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<bpws:process exitOnStandardFault="yes" name="Test"
    suppressJoinFailure="yes"
    targetNamespace="http://sample.bpel.org/bpel/Test"
    xmlns:bpws="http://docs.oasis-open.org/wsbpel/2.0/process/executable"
    xmlns:ns="http://sample.bpel.org/bpel/TestArtifacts"
    xmlns:ns0="http://test.com" xmlns:tns="http://sample.bpel.org/bpel/Test">
    <bpws:import importType="http://schemas.xmlsoap.org/wsdl/"
        location="Test.wsdl" namespace="http://sample.bpel.org/bpel/Test"/>
    <bpws:import importType="http://schemas.xmlsoap.org/wsdl/"
        location="AddService.wsdl" namespace="http://test.com"/>
    <bpws:import importType="http://schemas.xmlsoap.org/wsdl/"
        location="TestArtifacts.wsdl" namespace="http://sample.bpel.org/bpel/TestArtifacts"/>
    <bpws:partnerLinks>
        <bpws:partnerLink myRole="TestProvider" name="client" partnerLinkType="tns:Test"/>
        <bpws:partnerLink name="PartnerLink"
            partnerLinkType="ns:addServicePLT" partnerRole="partnerRole"/>
    </bpws:partnerLinks>
    <bpws:variables>
        <bpws:variable messageType="tns:TestRequestMessage" name="input"/>
        <bpws:variable messageType="tns:TestResponseMessage" name="output"/>
    </bpws:variables>
    <bpws:sequence name="main">
        <bpws:receive createInstance="yes" name="receiveInput"
            operation="process" partnerLink="client" portType="tns:Test" variable="input"/>
        <bpws:reply name="replyOutput" operation="process"
            partnerLink="client" portType="tns:Test" variable="output"/>
    </bpws:sequence>
</bpws:process>

partnerLinkType声明如下：

<plnk:partnerLinkType name="addServicePLT">
		<plnk:role name="partnerRole" portType="wsdl:AddService"/>
	</plnk:partnerLinkType>
    <import location="AddService.wsdl" namespace="http://test.com"/>
