Fix Version/s: 2.3.2

Added to the release notes
> 2.3.1 throws exception for java bean specification violation (2.3.0 not)
> ------------------------------------------------------------------------
>
> Key: IBATIS-501
> URL: https://issues.apache.org/jira/browse/IBATIS-501
> Project: iBatis for Java
> Issue Type: Bug
> Components: SQL Maps
> Affects Versions: 2.3.1
> Environment: ibatis-2.3.1.710
> Reporter: Kai Grabfelder
> Assignee: Clinton Begin
> Fix For: 2.3.2
>
>
> Assume the following class com.foo.bar.Bean with the following methods:
> void setFoo(int)
> void setFoo(String)
> int getFoo()
> I'm using this bean in an implicit parameter map as a parameter to an select
> statement that looks like this
> <select id="getIds" parameterClass="java.util.Map"
> resultClass="java.lang.Integer">
> select * from dual where 1 = #bean.foo#
> </select>
> with the bean being a property of the map. This statement is working with
> iBATIS 2.3.0 but iBATIS 2.3.1 throws the following exception when executing
> the select:
> Could not get property 'foo' from com.foo.bar.Bean. Cause:
> java.lang.RuntimeException: Illegal overloaded setter method with ambiguous
> type for property foo in class class com.foo.bar.Bean. This breaks the
> JavaBeans specification and can cause unpredicatble results.
> This exception makes sense when it comes to actually using the setters but as
> only the getters are used I think it should not be thrown. It is perfectly ok
> for me, if you consider this as won't fix, but please at least mention the
> change in the release notes because it breaks backward compatibility.
> See below for the relevant parts of the stacktrace
> Caused by: com.ibatis.common.beans.ProbeException: Could not get property
