Niall Pemberton commented on BEANUTILS-334:
-------------------------------------------
One of the problems with BeanUtils prior to version 1.8.0 is that the parsing
of property names (nested/indexed/mapped) was duplicated in several places and
was inconsistent.

It was because of this type of inconsistency that the parsing of property names
was extracted out into a Resolver[1][2] (see BEANUTILS-259) so that from
version 1.8.0 it would be consistent accross BeanUtils.
Can you confirm the property name that your application is faling on (you can
turn on logging in debug mode to see what BeanUtils is doing) and also whether
you think this is an error in your application uncovered by the stricter
parsing in the new Resolver or whether you think there is a valid use case for
this scenario.
If there is a valid use case then perhaps one solution would be to provide
strict/lenient modes for the default Resolver to operate in. In the meantime
you can plug in your own customer Resolver[3] implementation to work round this
scenario - something like:
BeanUtilsBean.getInstance().getPropertyUtils().setResolver(...);
