How much compatible Java 1.2 & 1.4 interfaces?
Where can I get the compiled list of such interfaces which are not compatible?

How about:

But I think you'll find 99.9999% of everything is UPWARD compatable.
That is, if it ran under the old release it will run under the new.
Even 1.4 to 1.5 (5.0) things are mostly clean in an upward direction.

Notable exceptions that I've run across include:

1. Some low-level code that implements standard API interfaces, such as
JDBC drivers.

2. Any moderately complex code dealing with component focus management
in Swing.
