Getting error "After parsing a valid expression, there is still more data in the expression: 'lcurly({)'" - spring

Question

I am using Spring-Integration for my project. I am experimenting with reading of the property/constant values from xml file (instead of .properties file).My xml file in which the properties/constants are placed is as below:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<persistence>

</config>
Now, I am trying to read the above values in spring integration configuration files as below:
<beans
<import resource="spring-integration/Jobs/*.xml"/>
<!-- map of namespace prefix to URI -->
<util:map id="xmlMessageNamespace">
<entry key="SOAP" value="http://schemas.xmlsoap.org/soap/envelope/" />
</util:map>
<int:channel id="jobDesignerInputChannel" />
<int:channel id="cs-exceptionHandlingChannel" />
<bean id="msgHandler" class="com.dsths.cs.awd.jobs.PQMessageHandler" />
<!-- TODO: Following lines are commented out as part of POC.-->
<!--<bean id="xmlAggregator" class="com.dsths.cs.awd.jobs.XmlAggregator" />
<bean id="httpOutboundGatewayHandler" class="com.dsths.cs.awd.jobs.HttpOutboundGatewayHandler" />
<!--<bean id="xmlFilter" class="com.dsths.cs.awd.jobs.XmlFilter" />-->
<int:chain input-channel="jobDesignerInputChannel" >
<int-xml:xpath-header-enricher default-overwrite="true" should-skip-nulls="true" >
<int-xml:header name="${customerservice.headerNames.legacySystem}" xpath-expression="//LegacySystem" evaluation-type="STRING_RESULT" overwrite="true" />
</int-xml:xpath-header-enricher>
<!-- Some of the AWD jobs contain Business Area info under <code> tag, we should not keep that business area info in the
header since it is not required.This will help us in identifying AWD and Non-AWD jobs-->
<int:header-enricher>
<int:header name="${customerservice.headerNames.businessArea}" expression="#xpath(payload, '//businessArea/Code', 'boolean') ? null : #xpath(payload, '//businessArea')"/>
</int:header-enricher>
<int:router expression="${customerservice.routing.jobChannel}"/>
</int:chain>
<int:chain input-channel="cs-exceptionHandlingChannel">
<!-- Service Activator to handle the errors -->
<int:service-activator ref="msgHandler" method="handleError" />
<!-- Router to routing the error messages to appropriate job channel for xsl transormation -->
<int:router expression="${customerservice.routing.jobErrorChannel}"/>
</int:chain>
</beans>
But, unfortunately I am getting the following exception when try to read the properties from the xml file:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.handler.MessageHandlerChain#3': Cannot create inner bean 'org.springframework.integration.handler.MessageHandlerChain#3$child#2.handler' of type [org.springframework.integration.config.RouterFactoryBean] while setting bean property 'handlers' with key [2]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.handler.MessageHandlerChain#3$child#2.handler': Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:

Anybody have any idea where I am doing wrong?
Please let me know if my question is not clear.

According to the StackTrace your issue is here:
<int:router expression="${customerservice.routing.jobChannel}"/>
Before to use such a difficult configuration you should be sure that your customerservice really returns all desired options.
Would be great, if you had shown how does that object look from Java perspective, rather than XML background
