Christopher L. Shannon commented on AMQ-6120:
---------------------------------------------
The activemq-spring sub project is where the spring stuff lives.
[xbean-spring|http://geronimo.apache.org/xbean/] is used to generate the schema
from the java classes. This might be something that needs to be fixed in the
schema generated by xbean-spring, not sure. I think the problem is that it
isn't even passing schema validation to get to the part where the expression
can be evaluated because during validation it errors trying to convert the
expression to an integer. So it might be that the schema would need to be
fixed to relax validation.

> Reporter: Mark Anderson
> Priority: Minor

> I'm attmepting to use SPEL to configure the recoverDuration attribute of
> timerSubscriptionRecovery policy as follows (based on SPEL suggestion at
> http://stackoverflow.com/questions/18265518/using-spring-expression-language-to-define-xml-attribute):
> {code:xml}
> <amq:policyEntry topic="mytopic">
> <amq:subscriptionRecoveryPolicy>
> <amq:timedSubscriptionRecoveryPolicy recoverDuration="#{
> T(java.lang.Integer).valueOf('${my.property}') * 1000 }" />
> </amq:subscriptionRecoveryPolicy>
> </amq:policyEntry>
> {code}
> However, this results in the following error on startup:
> {noformat}
> org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line
> 1125 in XML document from class path resource [appserver/spring.xml] is
