bean validator issue in jdk 6

[Andrea Nasato]

Hi to all,

I'm using spring-modules-validation (0.7) BeanValidator with annotations
and I have a strange problem. If I deploy my web applications in Tomcat
running with jdk 5 everything goes well, but if I switch to jdk 6 I get
  a java.lang.NoClassDefFoundError.

This is a snippet of the configuration file of my web app:


<!-- This is the annotation validator -->
        <bean id="validator"
class="org.springmodules.validation.bean.BeanValidator">
                <property name="configurationLoader" ref="configurationLoader"/>
        </bean>
        <bean id="configurationLoader"
class="org.springmodules.validation.bean.conf.loader.annotation.AnnotationBeanValidationConfigurationLoader"
/>
<!-- Abstract Controller -->
     <bean id="abstractController" abstract="true">
         <property name="conf">
             <ref bean="conf"/>
         </property>
         <property name="validators">
             <ref bean="validator"/>
         </property>
         <lookup-method name="dao" bean="daos"/>
         <lookup-method name="blo" bean="blos"/>
     </bean>

and this is the exception:

Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Could not
instantiate bean class
[org.springmodules.validation.bean.BeanValidator]: Constructor threw
exception; nested exception is java.lang.NoClassDefFoundError: Could not
initialize class org.springmodules.validation.util.LibraryUtils
         at
org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:253)

Anyone has the same issue?

Thanks in advance

Hi Andrea,

Thanks for your answer! Is this issue somewhere in Jira? (I just want to
make sure this gets resolved for the next version :-)

Regards,
