bean validator issue in jdk 6

[gtrev]

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 application to Tomcat
running with jdk 5 everything goes well, but if I switch to jdk 6 I get
a java.lang.NoClassDefFoundError.

This is my configuration:
* linux;
* jdk 6;
* tomcat 5.5.20;
* spring 2.0.2;
* springmodules 0.7;
* maven 2.0.5 (I use the ibiblio springmodules jar);

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)

I found the same problem if I use winxp: jdk5 works and jdk6 fails.

Anyone having the same issue?

Thanks in advance

I solved the problem upgrading to commons-lang-2.3.
The validation framework declares a dependency to commons-lang-2.1 which hasn't got SystemUtils.IS_JAVA_1_6.

Before loading AnnotationValidator, the ValidatorNamespaceHandler checks if the vm has annotations enabled, using LibraryUtils.JDK_ANNOTATIONS_SUPPORTED, which is:
SystemUtils.IS_JAVA_1_5 || SystemUtils.IS_JAVA_1_6;

In java 5 the first part of the boolean expression returns true and the second isn't evaluated ---> No problems

In java 6 the first part returns false so the second is evaluated ---> using commons-lang-2.3 solves the problem

By the way, this is a very nice framework, it solves a lot of problems for me: I don't like very much validating against an xml

bye,

SystemUtils class is present in the common lang jar -
org.apache.commons.lang.SystemUtils
