[Springframework-developer] Backward compatibility issue

[Alef A. <al...@jt...>]

A user on the forum =
(http://forum.springframework.org/viewtopic.php?t=3D2034&start=3D0&postda=
ys=3D0&postorder=3Dasc&highlight=3D)  noticed a backward compatibility =
issue. I'm posting it here as well and have already replied on the =
forum.

It might be wise to include a known-poblems section on the website =
somewhere. They are minor issues, but still I think it's good to let =
people know if there is any issues.

regards,

Alef

I had a txProxyTemplate bean defined in my applicationContext =
configuration without the abstract=3D"true" attribute and things ran =
fine with Spring 1.1.1. I upgraded to Spring 1.1.2 and get an =
IllegalArgumentException stating that the template bean *must* have the =
abstract=3D"true" attribute if it does not declare a 'target' property.=20

I went ahead and added it and it was not a big deal. I'm not saying that =
the IllegalArgumentException thrown under this circumstance is bad, but =
given the prior behavior, it would have been nicer if it simply logged a =
warning since the new behavior does break backward compatibility.=20
