MethodInvokingFactoryBean error in 2.0.3

[alex.arana]

Hi all,

I'm currently migrating from 1.2.8 and came across this error while using MethodInvokingFactoryBean to read a property from a properties file:

...

After receving this error, I decided to test the above using the sample configuration code provided in the Javadoc documentation for
org.springframework.beans.factory.config.MethodInv okingFactoryBean (copied verbatim):

  <bean id="sysProps" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass"><value>java.lang.System</value></property>
    <property name="targetMethod"><value>getProperties</value></property>
  </bean>

  <bean id="javaVersion" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject"><ref local="sysProps"/></property>
    <property name="targetMethod"><value>getProperty</value></property>
    <property name="arguments">
      <list>
        <value>java.version</value>
      </list>
    </property>
  </bean>

And this is the error I received:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'javaVersion' defined in class path resource [com/someapp/application/spring-inc-txn-mgmt.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodException: $Proxy53.getProperty(java.lang.String)

Has anyone encountered this issue before? Alternatively, can anyone suggest a workaround?

[Andreas Senft]

I cannot reproduce this problem with Spring 2.0.3. What I find curious is that "sysProps" seems to be a proxy in your case. Could it be that there is an interference from autoproxying?

Regards,
Andreas

It's usually useful to see the whole applicationContext here. There does seem to be some proxying, but from the snippet it's not clear where this is coming from.
