[jira] Created: (BEANUTILS-384) ConvertUtilsBean unable to process javassist classes

ConvertUtilsBean unable to process javassist classes
----------------------------------------------------

                 Key: BEANUTILS-384
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-384
             Project: Commons BeanUtils
          Issue Type: Improvement
          Components: ConvertUtils & Converters
    Affects Versions: 1.8.3
            Reporter: smallufo


The ConvertUtils uses ConvertUtils.register(userConverter , User.class) to register a converter.
And use converters.get(clazz) in Converter.lookup() to find proper converter.
It won't work for javassist modified object . 
for example , the User.class runtime becomes User_$$_javassist_0.class , and Converter is unable to find the corresponding converter.

So , I suggest the future version can loop the converters map , and use User.class.isAssignableFrom(clazz_in_map) to find corresponding converter.

Niall Pemberton commented on BEANUTILS-384:
-------------------------------------------

Switching from a straight Map.get() to looping over all entries to find a converter may have a negative impact where BeanUtils is heavily used.

You can override the ConvertUtilsBean's lookup(Class, Class) method to implement this behaviour yourself and then register your custom ConvertUtilsBean using:

{code}
BeanUtilsBean.setInstance(new BeanUtilsBean(new CustomConvertUtilsBean()));
{code}

------------------------------------

Hi , I think I need to override lookup(Class clazz)
but I cannot get converters in CustomConvertUtilsBean , because converters(map) is private , not protected.
