ww:text tag returns an invalid value for an i18n key that starts with the same name as an action variable

Create a simple action TestAction with a field variable foo and a getter/setter for the foo variable. (getFoo(), setFoo()). In an i18n file, create two keys, foo.bar.baz and bar.baz. In your action resule, use the <ww:text> tag to retreive an i18n key 'foo.bar.baz'. The value that gets returned is the value of the key 'bar.baz' not the key 'foo.bar.baz'.

This happens only when there is a getter method for a field variable with the same name as the start of the i18n key. If you rename the field variable or the start of the i18n key, everything works as expected.
