Any way to support expando props on Java objects?

[Sundararajan Athijegannathan]

Hi,

Haven't gone through the referred code. Do you want to add more 
properties to a Java object apart from "bean properties" inferred?

If so, you can write your own dynalink linker with jdk9.

API doc:

Sample:

Hope this helps,
-Sundar
