Spring 3.2 MVC @RequestParam unexpected decoding

Consider following query string

siteId=360798&listingId=695332&stockFilename=6065/1mb%20&%20(Custom).jpg&uploadToken=2640861a8f06799416bae9d0a58839dd&username=Chuck%20Norris

I have the following on my MVC controller

@RequestParam("stockFilename") String stockFilename

I expect to get as value in my param to have "6065/1mb & (Custom).jpg", yet the result is "6065/1mb". My first guess was that this was an encoding issue so I went to web.xml and looked at my encoding filter but this seems to be in order

<filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

Next up I went to look at my server setting

Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"

I've added the URIEncoding attribute, since I found an article explaining this as a possible culprit. However it didn't fix my problem at all. I'm actually out of ideas now I'm still quite sure it has to be an encoding issue, and spring is decoding it wrongly. I'll continue searching but any help would be appreciated.

Add this method and bean in your servlet-context :

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

public final class DoNotTruncateMyUrls implements BeanPostProcessor {
    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        if (bean instanceof RequestMappingHandlerMapping) {
            ((RequestMappingHandlerMapping)bean).setUseSuffixPatternMatch(false);
        }
        return bean;
    }
    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
        return bean;
    }
}

Bean :

<beans:bean class="com.packagename.DoNotTruncateMyUrls" />

Let me know if this works, or I have another solutions.
