Matt Drees updated JBSEAM-1257:

    Attachment: reflexive-equals.txt

Here's a patch to JavaBeanIntereceptor.java that should do the trick, I think.  When intercepting an equals method, if the parameter is identical to the proxy, it unwraps the parameter.  So I suppose if you design your equals method to make calls on the parameter assuming interceptors will be run (for injection, etc), then this patch would hurt you.  But I think no one should be making those assumptions for an equals method.

> If a javabean component doesn't override equals(), the javassist proxy generated for it has a nonreflexive equals method.  I.e., component.equals(component) returns false.
